It was a pleasure to stay at Jutta's flat.
Nice, clean, very well situated and can easily accomodate up to 8 persons ( 3 bedrooms, so do not forget your earplugs if you share it with other snoaring guys ;.-)
One Bedroom ( the one not on the street side) is very silent , the 2 others are on a busy street and depending on the alcool level of the crowd in the street it can be noisy, but you can't be super well situated in the middle of Barcelona and completely avoid any noise....
