If it were possible I would give this a 4.5 rather than 5, so I rounded up because Luis is such a nice guy.
The pros:
Location. El Born is a wonderful neighborhood, filled with restaurants, bars and boutiques, mostly on charming narrow streets. On occasion it can be noisy outside, but not too often.
Space. The apartment isn't that large, but it's large enough. The bed is comfortable, and while the water pressure in the shower isn't great, it's good enough.
As I said earlier, Luis is a really nice guy, and very responsive when there are issues.
The cons:
Parts of the floor in the living room and the kitchen are cracked or broken. It never felt dangerous, but it would be nice if they could be fixed.
The chairs in the dining room range from mildly uncomfortable to very uncomfortable.
All in all, being in such a good location and getting a good night's sleep made for a very nice two month stay.
