I was planning on staying in Fiducia for four nights, but had to find another hotel the first day. There is no hot water in the shower, and the room is full of mosquitos nesting in the plumming. I come from a country of mosquitos and am not troubled by a few, but it was impossible to sleep with the buzzing and the itching! Also, there is indeed aircon, but you don't get a controller for it, since there is only one remote for all the rooms. So whenever you feel too hot or cold, you have to ask the staff to come and adjust it.
The one nice thing in Fiducia is the staff, they are quite helpful and friendly, although not all of them speak good english.
All in all, even if it is quite cheap, I would not recommend this hotel.
