We stayed 7 days in the double bed room at Carlos house and our first impression was like - 'wow, this room is tiny', but everything else recompensed this little inconvenience. Breakfasts were great - made by Carlos himself, localisation was great - 10 minutes to La Rambla/Barri Gòtic. Carlos gave us advices where to go, which bar to choose, which tickets to buy, where to buy cheaper etc.
Our daugher really got to like Carlos (how's your flowers? :))

At the end of our stay we were stolen from our backpack and Carlos helped us a lot - he lent us a cash (we've lost our debit cards), took us to photograph to take photos to our temporary passports, took us to the consulate by his car and finally he gave us a ride to Girona airport (at 3 a.m.) - 1 hour one way.

Despite robbery we really enjoyed our stay in Barcelona and we reccomend his house as a very nice place to rest.
