Overall, the stay was ok. The staff is friendly. The food at both breakfast and dinner was good. The location is great. Where it went wrong was the fact that there is no AC.
My room was 27c. The option to open the windows for ventilation was a non-starter, as my room was on a busy street with too much traffic and noise from the restaurants across the street. Their answer is to provide earplugs. Not a good answer. They also provided a small fan. It helped, but not much in a 27 degree room with effectively no windows.
I understand this is an eco-friendly hotel, but most people cannot sleep well in a room that hot.
