On his page, it says he has free private parking and I also explicitly ask him on private msg if this is true and he said it is. Upon arrival, we realised that we need to park in public parking which is NOT free and because the apartment is located in the center this is really hard.
The other thing that was bad is the air in the apartment. The apartment has 2 small windows and it takes a long time (~4h) ventilate.
Diego speaks okay English so the communication was fine. He was also willing (without any complications) to change our booking dates (we left 1 day earlier because of the things mentioned above). This shows that Diego is a professional and he knows how to handle these situations.
