We had a great stay in the flat. The flat is highly recommended for a stay with a group as each of the four rooms has its own bathroom and people can have some privacy.
It perfectly located in the city center, so with few minutes walking you can get to the important sights, all important squares, the cathedral, museums, restaurants, shops, supermarkets and so on. To the beach it is 15 minutes walking distance. It is a good neighbourhood, close to Picasso's birth place.
The flat itself was clean and well equipped with the things that you could need during your stay. The beds were comfortable and everyone slept very well at night, also because it was quiet. We had 2 keys, but as there is a box for the keys at the entrance, it is easy to share the keys with the rest of the group.
Maria was very friendly and the communication was quick.
