Our stay in Maria's appartment was really great, very big appartment with 6 beds, well equiped, well located. You have everything you need around and it's easy to go to the center from her place.
However, there are 2 bedrooms which are on the street side and unfortunately, in the morning, the noise may disturbs you a little. But generally speaking, everything was great.
I just would like to thank Maria for her help and for the flexibility of the check-in and check-out. Thank you too for all the tips you gave us.
We will definitely come back to Barcelona.
