This house is simply great. We were 8 people and we had an awesome time there. The house was big enough for the 8 of us. 4 big double bedrooms, and two complete bathrooms. Charles is a very nice host. He took care of us, and checked that everything was perfect for during our stay.
The location is more than ok, just 10 mins walking to the Paseo de Gracia, and right in front of a metro station.
I would totally come back to this house if I have the chance.
