We liked the location of the place as it is very central, but still in a street with almost no cars. Everything's very easy to reach in short walking distance.
Overall, you get all pros and cons of an apartment in an old building. The ceiling is high and the main room has huge windows, which is beautiful. If you're travelling when it is 15C outside, consider that the apartment is not very well heated and you should have warm clothes at home. You can basically hear every movement in the hallway / staircase. When we were there (March 2018), there was a construction work in the street starting quite early.
We had a big problem with the shower drain as the water was not running down (apparently it did but very slowly), nevertheless Dulce tried her best to solve the issue - thanks for that!
