The location is amazing, the apartment has windows to the inner block so it was also very silent. Heating and everything else worked perfectly fine. The apartment is renovated, clean and pretty.
The room with one bed had the only openable window to the inside of the house hallway, which was ok in winter, but I can imagine it might be a bit unpleasant in summer, when you want to open a window to the outside to get some fresh air. The night of our arrival was a bit hectic because the apartment wasn't ready for us, but despite the late hours (2 am), Raul came and offered us another apartment and refunded the money for the first night.
