The apartment is located in a very nice neighborhood, not far from L4 subway station.
The check in and check out were very flexible (we were given an access code) . It was clean, with all the amenities we needed for our stay (including cooking). The WiFi isn't fast but enough for basic browsing and email. TV offers only few channels but you don't need it in Barcelona. The city is beautiful and easy to reach from Espais Blaus Apartments. We highly recommend it.
