The comments made about Le Fenix being a bit run down and showing its age are spot on, but the price reflects that and you get what you pay for. The hotel is well designed and the rooms are comfortable enough.
The location is okay, being on the dog leg in Soi 11. The walk to Sukhumvit is decent, around 15 minutes or so. There are plenty of nice restaurants and bars near Le Fenix, so you don’t have to go down to Sukhumvit all the time.
My room was good, and the fittings were all functional and comfortable. The bathroom was very small, but okay. Staff were friendly and helpful. As has been mentioned before, you get 2 hours free WIFI. There are several restaurants in the hotel, so dining in is a real option.
Le Fenix is now an old hotel, and things are getting worn out, but it still remains a comfortable hotel and a good option for a cheaper hotel in Bangkok.
