I had such great time at Marcel's flat. I spent 10 days in his 1 bed room where I could work thanks to his fast internet connection. I felt home, the appartmenthas everything you need.
the only thing to know is that the flat is located next to parc guel on top of the hill.
if you dont like hiking it is going to be a real effort for you to go home by walk.
besides that everything is perfect. I definitely recommend.
