From the first moment we had great contact with María, she even helped us book a taxi and was very kind, helpful and commucative. The appartment is just as good: very clean, spacious, complete (has everything you need and more, even netflix!) and it's in a central location near a lot of cafés, restaurants, supermarkets, etc.
The appartment is on the 3rd (?) floor, on a quite busy side street off the Plaça de l'Ajuntament with nice options for lunch and dinner. This also means that it can be quite noisy late in the evening. However, this is the only (minor) downside I could come up with.
