Finn's apartment in Barcelona is fantastic. Just the right size for my wife and myself. I could bring one of my kids and it would still be perfect. We stayed a week after landing in Barcelona.
First: The apartment contains all the basics for a person like me. I was able to cook some basic meals and I like to try out all the local food. Able to keep my travel kit in fresh condition as there is a washer in the apartment and clothes line on the patio. Oh, the patio, the site of some fabulous meals and late night conversations under the Barcelona stars. The mattress in the bedroom is not hard, we slept like a babies. For my American friends CNN in english on the tv.
Also very important, very quiet location.
Location: My personal preferences are to walk about in cites and this location was perfect. We used the local subway to connect with distant parts of the city. Caught the On and Off tour bus at the Familia, 2 blocks away and got the lay of land. Used taxis late night and the most we spent to get from one side of the city to the apartment was $10. Walked from Park Guel to the apartment in 25 minutes all down hill. There are at least 4 super markets with in 3 blocks, a butcher shops, Iberico pork shop, organic vegetables and fruit shops really closed. Restaurants everywhere and do not be afraid to try the tiny ones tucked away down the narrow back streets.
All in All: My wife and I are coming back!
