Mar's place is nice and clean. It has everything you need. It is excelent located with a connection to metro and public transport stations. You can go to the city centre in 10 mins. There are a lot of shops, restaurants and bars near the place. The host was very nice and helpful. He shows us where are the shops and how to get to some places that we wanted to visit. Also he answered quickly on every question we had. I definitely recommend it for your vacantion in Barcelona!
