All in all I had a very pleasant stay at Rubén’s place :)
His communication was great from the beginning and even returned to Barcelona earlier to make sure I checked in safely when his flat mate had to make some errands. He took into account the hot weather and checked if any fans where needed etc and responded to questions well!
The only thing is be aware that other air bnb guests may staying at the same time as not made aware, but luckily my experience with the others was great and everyone I met was very kind!
I would stay at this location again. Thank you!
