The communication with Ana and Joao before the check-in was very easy and good, they were flexible and on time and replied fast. When we arrived Ana was there to welcome us. As we arrived when it was already dark we didn't recognise the slightly wet air and moldy smell as an issue. The flat was not perfectly clean and only has one big and 2 very small windows of which none is in the bed- or bathroom, but it was all acceptable. Some days later though, we saw more and more moldy stains on the walls, ceiling, behind furniture etc. and after the weather got wet it was not possible to get the moldy smell and humidity out of the flat anymore. I felt that, after nearly a week, it affected my health in a way that made me decide to change the Apartment a week early. I know it's an old house and not easy to prevent, but I can't imagine it to be healthy to stay there. Also you could hear everything from the neighbours and especially their dogs also during night time, which can be an issue for people that can't stand a lot of noise.
