We definitely recommend staying at this place!
We were a group of 11 people plus 2 babys - and all of us were really happy! The rooms are big, clean and very comfortable. we love the big terraces!! In general the house was very, very clean with nice furniture.
We could leave our luggage before the check-in and also before the check-out. Communication with the hosts was also great.
The location of the house is just 20min by foot from Gracia - where there are a lot of bars and cafes. A few restaurants are also just one street further. but its just 2 min to the next metro that leads you directly to gracia or plaza catalunya.
Thanks for the great accommodation and thus for the great time in Barcelona!
