Mauro was a very welcoming and accommodating host that has added some lovely touches to the house to make you fee comfortable. We were two families of four with kids aged 7 and 9 and we fitted in well although it was a bit tight (however, you spend little time indoors in Barcelona!). The apartment is set out lengthwise so there is some privacy between groups staying. The location is great - quiet, not touristy, and close to some great sites. We walked most of the time but also caught the metro which was close by. Supermarkets, a fruit/veggie market and fabulous restaurants are right at the doorstep. The road the place is on is a bit busy and loud during peak times but did not bother us.
