The building is very nice, and could be just amazing if the owners improved some really basic features that are completely lacking or simply insufficient.
I have experienced two rooms: one double (supposed to be "superior", according to the receptionist) and one single (the only single room at the property, as I have been told), and both were extremely dark, without any window or opening for light and air. Artificial lighting was completely insufficient too, just one single light bulb on the ceiling with very low power, no other lights near the bed. Briefly, it was impossible to read in the room or even see where your own things were.
The micro toilet was placed into the same room behind a moving panel, and the sink and shower were terribly smelling.
Breakfast was quite poor too and service not very friendly and helpful.
The price is low, it's true, but not worth at all, and I suggest to pay few euros/dollars more to get a much better and decent accommodation.
