What a wonderful apartment and this wonderful apartment gave us the opportunity to have a great vacation in lovely Barcelona! First of all, location! you have Sagrada Familia just around the corner and the metro of course, so it's impossible to get lost. We were 4 and we were very comfortable with all the space in the house, kitchen, bathroom, sleeping rooms..
I never met Daria or Xavi but check-in and check-out were very very easy. They are like the best hosts ever! So kind, easygoing, to sum up it was all great! Very clean and comfortable apartment, everything you need! Don't even hesitate, this is the best choice in Barcelona with its best hosts :)
