We absolutely LOVED our stay in Alex's beautiful, spacious apartment. It was genuinely superior to staying in a hotel, with the great kitchen and large bathroom. Alex was very helpful, providing all sorts of info on getting around and even restaurant recommendations. He went out of his way, too, in helping me find a local Catalan chef to hire for a cooking class, right there in the apartment.
The location was great, just a short walk to the metro line and you could go anywhere, and walking distance from plenty of unforgettable sights.
This was our first trip to Barcelona, so it really helped to have someone there to share that info that only local residents have.
Just excellent.
