I really enjoyed my stay at the Nysa when I was there in June. Have just managed to snag 6 nights leading up to Xmas at a very reasonable 2500b / £57 a night vs the Mercure which is 4400b / £100 a night so a no brainer really. 

Thanks to everyone's contributions, pictures and descriptions are lovely, it feels like I'm eating vicariously through your words. Cheat away @Genghis please!  

First stay at the Nysa Hotel, which belongs to the same ownership group (Kingston) as the Solitaire, Pipa, Samala, Aira, Eleven, and many others in BKK. First impressions: Check-in was smooth and courteous. Took just a few minutes, but I checked i at 10pm. I saw a crowd of 30 mid-morning the next day. Glad I missed that. Room (see pics below) Positives- --Spacious, lots of light for rooms on the upper floors (I'm on 6 of 7) --Very comfortable bed, with good quality linens --Room was spotless when I checked in --Lots of closet space and room for luggage storage --Lighting is good, controls are accessible --AC is great and easy to control --Plenty of electrical outlets for charging devices --Good TV across from the bed, with Netflix access if you have an account. --Minibar, free water (4 bottles/day), coffee and tea maker --Great bathroom, with separate tub and shower (rainfall and handheld wand) --Controls in shower are easy to use, plenty of hot water, excellent adjustable water pressure --Very good bathroom amenities (shower gel, shampoo, conditioner, hand/body lotion, toothbrushes for guests) Minuses- --Desk/Work space. There's no desk in the Pool View room, just a table and a chair. Limited workspace on that table. --Odd furniture. Look at the pictures below. Along the wall opposite the bed there's a long hard surface, presumably for luggage, and a long bench that strikes me as useless, and not especially comfortable to sit on. The chaise to the side of the bed is also a bit odd, but at least I can have some fun with the girls on it. I'd much prefer a small sofa or a couple of chairs. --Internet. It is often slow, slow, slow! There's no excuse for such shitty service at a nice hotel   The Hotel more generally Location: Just around the corner from CIB11, so easy access to all that Soi 11 has to offer. Walking back to the hotel from CIB11 or Cindy's Secrets is a breeze. This section of Soi 13 is very quiet, with almost no traffic. You can cross the street without taking your life into your hands. And consequently the rooms are very quiet. I've not heard any street noise. Access- The hotel is entered trough doors off of the driveway on Soi 13. To the left is the concierge desk and to the right the check-in desks. Both elevators to guest rooms are accessed by going past the check-in desks. One set of rooms are reached by the elevator just past check-in, the other set by an elevator located near the restaurant entrances. If you return with a guest there;s a good chance you'll see other hotel guests on your way to the elevator. I'm shameless, so I don't care. Gym- is located on the ground floor, just beyond the check-in area and to the right. The gym is basic, with the usual cardio and free weights, but otherwise somewhat limited (The gym at the Mercure is smaller but better equipped). One odd aspect is that you are visible to people walking by the hotel while you work out. Pool- is very nice, located on the first floor with the entrance near the restaurants. I've noticed that in the early afternoon the lounges and seating are sometimes completely occupied. Most of the seating is well shaded for most of the day. Towels are available at the pool. Most people bring a bathrobe from their room with them to wear when they make the trek back to their rooms. Breakfast- My room rate came with complimentary breakfast (as special offered at the time I reserved). I normally wouldn't pay for hotel breakfasts. This buffet was a bit disappointing, heavy on the Asian and Indian offerings, light on the Western ones. It was the standard egg station, and places to get breakfast meats, potatoes, breads, pastries, juices, fruit, and drinks. Most everything was underwhelming. Pastry and bread offerings were minimal, same with fresh fruit. Pretty ordinary for such an otherwise nice hotel. I'll be skipping the free breakfast often. Clientele- The place feels less like a BKK monger hotel than, say, the Mercure. While there's a mixed clientele, I'd say it's probably 50% Indian/South Asian, with a healthy smattering of Europeans. Also there' are lots of couples and quite a few families with kids in the mix, more than I've seen at the nearby Mercure. I have seen very few of the Indian customers at the pool or in the breakfast restaurant. I mainly see them in the lobby and elevators.
