Our stay in Barcelona was excellent. Marc explained us everything and was very nice host. Apartment was nice and clean, very close to the metro and Sagrada. There is a lot of tapas bars, small supermarkets and shops just on the same avenue as the apartment is, so if you want to go out just for a coffee or drink, you don't need to go far away. Barcelona is one of the nicest cities I have been in. Looking forward to come back again.
