I stayed for a month, the apartment looks exactly like the photos. Very well situated, you are 30min by foot for any direction in Barcelona. Taxi / Metro are next to the apartment.
WIFI is okay (50Mbs). I would say for a month it might be a bit long.
The only negative point was the A/C which didn't work, someday when it go up to +35° it can be annoying.
Oscar is a great host, available at any time!
Thanks Oscar!
