Alexandre's apartment is a joy. It's located close to green markets, grocery stores, cafes and coffee shops. Two blocks away is an entrance to the metro system which you can take almost everywhere.
The apartment has everything you should need, including a well appointed kitchen and a pantry of basic foodstuffs that are available on an honor system. The first night we arrived tired and starving. we were delighted to find pasta and sauce to cook so we did not have to go out.
Like a lot of apartments in Barcelona, this lovely place has three floors with steep stairs. If you are traveling with someone with a mobilty problem I would suggest you have them sleep on the couch on the lower floor. Other than that minor detail, this flat is a joy!
