This is a very good place. It's great value for the location. You are so near to Place d'Espana and Place de Catalunya both are easily walkable, especially Espana. There is a Metro stop a short block from your front door. A cafe as soon as you turn left. The bed in the apartment is one I would have taken home with me if I could have gotten it into my luggage. My only quibble about the apartment is that the shower is a tight fit. Of course, if you aren't as fat as me it won't be a problem.
Another review mentioned that the apartment is on the fifth floor but the elevator only goes to the fourth. This is true, but it's only a matter of fifteen steps and there are three landings so it's not like a trek through the Himalayas. The terrace doesn't have a street view but it would be lovely place to hang out in seasons other than December when we were there.
Seb is an expatriate American who is extremely accommodating (how many saw what I did there)!
Because we needed to drop our luggage so we could make a four o'clock kickoff for Barcelona F. C. Seb was there to assist us. Also sent me a message that I had left the tickets at the apartment and so I was able to retrieve them. He was helpful at every turn, responded quickly to all messages and requests for information, and is also there to arrange other activities as he works in the travel industry.
Great place, great location. Especially for young people who would like to explore interesting neighborhoods.
