Very nice and clean house. I recommend it 100%, I've never seen people so attentive and friendly, the dormitories, mattresses and sanitary facilities are in very good condition and clean. Thank you very much. 
We enjoyed our stay at Hotel Ganthera and the staff were friendly however the room itself could have been improved. For example, there was distinct black marks on the walls and some mould in the bathroom but we understand the climate is humid (also some dead bugs). Bed area was clean and satisfactory and we slept well.
The front door is locked at night so beware if needing to leave early - staff are not attentive to this.
Whilst we did not use the pool area, the view was nice and pool looked good. Overall we enjoyed our stay but would probably not come back.
