I chose Luis's apartment because we only had one night in Barcelona and wanted to be near the sites that we wanted to visit and also a quick ride to the airport. I didn't expect such attentiveness from our kind hosts Gemma and Luis. They are lovely people. They took good care of us with lots of great suggestions for restaurants and bakeries.
The apartment is simple, clean, and well located (only a couple blocks from Sagrata Familia). It is inherently charming with brick walls, exposed vaulted ceilings and beautiful hand made wood doors and woodwork throughout.
I would absolutely stay here again.
