It is an amazing flat within a really nice district of Lisbon, and we loved how everything looked inside.
Meanwhile, there is one big problem with the flat, or, if to be precise, with the bedroom - after the renovation of the old building, the humidity caused by the showers was not taken into account, so all walls were full of water, and we, as guests, were sweating throughout the night even with open windows. It should be taken into account while having next guests - I guess special humidity-deacreasing machines would be fine (I saw some sponge-based small machines on the Internet that make it amazingly easy), or change of the paint on the walls to the one that can be easy for the flow of air.
