I stayed at BYD Lofts with my fiancé for 9 nights and it was a fantastic experience.
The rooms were cleaned daily, the mini bar and restaurant services were affordable, the staff are helpful and friendly. Best of all was the location - away from the hustle and bustle of Patong but close enough to walk down to Bangala Road.
We only had one issue — there were cockroaches in the bathroom. However this seemed to be an issue more so with the whole of Patong than anything else.
