The flat is functional. It is run like an hotel with two other flats on the same floor. The walls are really thin, so you can actually be bothered by the life of the other neighbors.
It can be chilly during the winter, especially in the room because the AC (which can be turned on heat) is in the living room. it hasn't been taken in consideration. The duvet is so thin, when there is one (the big bed didn't have any), that you have to sleep with pull over and socks.
It's also difficult to sleep well due to the thickness of the mattress, especially in the room with the bunkbeds where you can actually feel the metallic bar in your back.
The day after our arrival, when we came back from the city, we discovered a flood with 5cm of waters in the kitchen, the living room and the bathroom... We stopped the water, we moved some of the furniture outside and started soaked up. Julia, who takes care of the flat, and then the owner come over quickly with a plumber. As they don't speak English and our spanish is quite bad, it was difficult to communicate. it took 3 or 4 hours in total when we had to be around. Our shoes and some of our books we just bought were destroyed but we thought it can happen everywhere. Then, we realize that the first line of the guide the owner left in the flat is "where to find the water mains inlet" and there is also a page dedicated to flooding...
After it was fixed, the whole flat was moist until we left... Humid from the floor, the wall and our clothes were always moist.
Even without the flood, we wouldn't have an happy vacation due to the lack of quality of the bedding which can perhaps explain the price.
