My boyfriend and I had a great stay in Luis apartment! It has everything you need, it's clean, enough space (also for two couples) and most of all Luis is one of the best host I ever met! He is really kind, helpful, for example showing us the apartment, flexible (we checked in earlier because other guests leaved earlier) and fast responding! There were even some drinks in the refrigerator! We also could our luggage drop at Luis house but he gave us a great tip that we could put our luggage in a locker near Plaça Catalunya (that was more convenient for us).
The location is also very good! Very close to Sagrada da Familia and the metro stations. Really recommend Luis appartement! And if you want a good breakfast or lunch choose the bakery El Taller de Su Pan (5 minutes from the appartement). They have the most delicious croissants and other pastery ever!!!!
