We booked this hotel through a travel agent who told us it was a 5 star hotel. I wouldn't rate it that high. It's a solid 3.5, 4 stars would be a bit of a stretch. The rooms were clean, spacious and smoke-free (which may be hard to find in Asia). The rooms felt a little old but still very clean. The pool area was very jungle-like which is pretty cool but it can get pretty dirty at times especially when it rained (which is practically everyday in Thailand!). What I loved most was that they made your bed every night with a little Toblerone chocolate.

The area seems a little deserted because it's mainly Embassies near by. It's a 5-10 minute walk to the Skytrain and 10 minutes from Central department store. It's definitely not the place to be if you plan on just walking out of your hotel and experiencing night markets, bars, restaurants, etc. We took taxis everywhere. You can walk during the daytime but at night it's deserted so be careful!

We chose this hotel after great deal of research because it looked like a calm oasis in the middle of a very busy city, which indeed it was with its beautiful garden surroundings and pool. Unfortunately with a very busy two day schedule in Bangkok we didn't have time to fully make use of the leisure facilities. Next time!!
Apart from a minor mix-up re our weekend package deal we loved this hotel and the wonderful staff who could not have been more gracious or helpful.
We arrived early after an overnight flight from Europe expecting only to be able to leave our luggage until later in the day but the lovely people had a room ready!
The room and bathroom were beautifully clean and spacious, and furnished in a restful minimalist Asian style.
The weekend buffet breakfast was great, as was the Saturday night seafood buffet that we enjoyed at the hotel.
We were also very impressed with the people in the business centre who happily assisted us in confirming and changing flights
All in all,a highly reccommended hotel which is ideal for people like us who prefer to escape the hustle and bustle for awhile but close enough to the sky train to allow easy access.

So we were pleasantly surprised when we got to this hotel. The view onto the pool and gardens was beautiful, and we almost didn't want to go to the tourist sites so we could spend more time enjoying the hotel. The location is a bit out from where the main tourist sites are, so it is a bit of a taxi ride to get there. But worth it to be out of the hustle and bustle of the city. We booked online well in advance, and got a great rate.

The food at the hotel was mostly western, and a bit spendy, but pretty good. The most amazing part was the spa - very inexpensive and excellent thai massages. Really amazing - to where we actually got massages 3 days in a row.

The rooms were spacious and nice, but I would not say over the top in terms of amenities. More equal to a 3.5 to 4 star hotel in the US. Clean rooms, and very good service. Concierge was always helpful. There is also a great bakery attached to the hotel where you can get coffee and teas, as well as croissants, etc. - we really enjoyed that as well.

This was our first stay at the Nai Lert Park. We’ve experienced a number of hotels in Bangkok. We’ve also lived in Bangkok as my wife worked for a small Thai consultancy and I spent a year lecturing at Thammasat University so we have a little more jaded view that your average tourists. The depreciation of the dollar plus regular inflation has made Bangkok hotels less of a bargain that they used to be. The hotel is next to the British consulate and near the Swiss, Vietnamese and American consulates. The sky train is within walking distance albeit a couple hundred meters.

We opted for a room on their executive club floor. When we arrived we were guided to the fifth floor for check in on the club floor. The internet rate was $175 before tax and SC. I appreciated the quick responses I received to my e-mails during the reservation process. I wanted to view a suite and the staff was happy to show us a room before we settled into our originally reserved room. The room was well prepared for our arrival, which was delayed by about 6 hours as a result of a cancelled flight. The lights were on, the bed had been turned-down with an orchid and chocolate on each side, personal bottles of water and even the television was on to an in-house music channel. We were exhausted and it was inviting and clean albeit a bit small. My only complaint was the ‘French’ doors to the bathroom - these frequently collided with the room door and were conducive to catching your finger between the doors – which I did twice. The room even contained an espresso machine with coffee pods – a nice touch.

We had the choice of breakfast in the lounge or the main buffet restaurant. The lounge had a limited selection but was more intimate and suited for business people wanting a quick bite before heading out for the day. The main buffet was well-stocked with good variety including some Japanese choices – the hotel hosts a number of Japanese business people. Our only complaint was that one morning my wife found a small cricket (cooked) in her vegetables. We shared this with the staff and they apologized replaced the dish. We’ve both eaten fried insects so we were not predisposed to ‘freak out’. I suspect the (foreign) chef would have been a bit more apologetic had he known.
I would try to get to breakfast before 8:30 as it fills up quickly as people drag themselves out of bed. There is an upscale French restaurant that we did not try as well as a Japanese eatery that we did try (average), and a bakery. The pool is free-form and suitable for cooling-off. The sense of a jungle resort is a welcome respite from the bustle of Bangkok. The fitness center is above average although crowded around 5pm as it is open to non-resident-members. The staff is generally well-trained. Indeed, I would say consistently better and friendlier than staff I have encountered elsewhere (Swisshotel Le Concorde, The Landmark, President Solitaire). The regular daily maid service was supplemented by the evening turn-down and tidy-up service. We arranged a car to the airport at 05:45 which was ready. The cost was a bit steep at 2,200 baht, about $66. However, it was a new BMW 7 series which accepted our 2 large suitcases and got us to the airport very comfortable and quickly with speeds as high as 140 kph (86 mph).
My litmus test for a hotel is very simple – would I pay to stay again. Yes.
