My girlfreind and I spent a week in Albert's appartment. Albert has been a great host. He welcomed us directly at the appartment and he answered all of our questions. It was easy to communicate with him, either before our arrival than during the week.
The appartment is located in a nice neibourghood, close to metro stations and right next to the beautifull Montjuic parc. They are many market places nearby and some nice tapas and pinchos bars too. The flat was super clean at our arrival and it is very well equiped. There is an elevator in the building, it can be usefull.
This flat contrubuted to our really positive experience in Barcelona. We highly recommand Albert as a host as well as his appartment.
