J. Walter’s apartment is a lovely, air conditioned place located right in the heart of old Barcelona. The location was well within walking distance to many good restaurants, a grocery store, the subway system, and many popular tourist sites, such as La Rambla, the cathedral, the Picasso Museum, etc. The owners were very friendly and offered great advice on where to eat, and how to get around. The owners have a charming gallery downstairs as well.
One should note that since the apartment is in the old district, an elevator is not available. If a future guest has any problem with climbing to a fourth floor apartment, this would not be the place for them. We did not consider it a problem though, and Roberto was very helpful with our bags.
