The apartment is nice itself, spacious, clean and close to some really nice areas. Host and the person, responsible for lending the apartment/keys were both very nice and helped with the small problems, that we had during our stay. The biggest problem was that there was no Wifi which was essential for me as i was on a business trip...so Ive spent a fortune on mobile internet. Although, that was probably my mistake too... as I havent checked this with the owner prior my travel ). Neighborhood was quite loud too. I would not recommend if you want quiet and if you stay a lot in. We`ve been woken up a couple of times during our night sleep and in the morning as someone was really loud..etc
Regardless these things, I have still enjoyed my time in Barcelona and thanks to Luis for letting me rent your flat :)
