We spent amazing time in Barselona, and one of the reasons is great Rosa's apartment. It is 5 min walk from metro and the same to the beach! The appartment is very spacious, clean and quiet. In the kitchen you can find any gudget you need for cooking. There are a lot of cafes and bakeries right near the apartment, so you can have fresh cakes and coffee for the breakfast.Rosa is very nice person. She gave us all the maps of the city. When we checked out, accidentally we left all our documents and passports in the apartment and Rosa was very polite to call us just in 15 minuts so we came back to get it.
So if you are looking for a place to stay in Barselona near the beach - I think it is the best one!!!
