All-in-all the place was great. What you see in the pictures is what you get.
The location is great with restaurants and shops close by, but the room faces a very busy street so it's not for light sleepers! Although the noise was something we got used to.
It was close to public transportation, but Barcelona is a walkable city. Minimum 15 minutes walking to most of the important sights.
You also share the apartment with 5 other rooms, but we didn't see much of the other guests. Sharing the 3 bathrooms was no problem.
We did have problems with the shower. The water temperature was unstable which was time-consuming.
Otherwise, the room was perfect for a long weekend with friends. We didn't meet Tomasz, but Mike was friendly!
