We had a great stay here! The location is absolutely perfect. Everything is in walking distance, and the tram stop is pretty much in front of the apartment (we used it to go to Plaza de Espana, super easy!). The beds were very comfortable and because there are two airco units, the apartment was nice and warm in january.
All the neccesities are available in the apartment to have a short stay in this beautiful city.
The only downpoints for us were that it could have been a little bit cleaner, although I would not say it was dirty, just a few little things, and the bathroom smelled a bit like sewer. Other than that, a perfect stay in a great location. Definitely worth your money!
