I really like Novotel Bangkok Ploenchit Sukhumvit. The staff are very kind, professional, and attentive. They remembered my name and went out of their way to help me at one point when I was in need to get a taxi to the other side of Bangkok. The location is nice, near the nightlife of Sukhumvit. I think my only wish would be that the air conditioning had more settings. It was always hard to find that sweet spot on the air conditioning that was not too hot but also not too cold. But aside from this, I really like Novotel. I would come back again.
