Clean flat with new furniture close to Placa d' Espanya. The host was very friendly and gave us some tipps on how to spend our time in Barcelona. The location is perfect to reach everything and close by to an insanely good restaurant (8th bowl). This place has another room you can rent, which is open to the main street and thus is brighter and easier to ventilate. This one has it's window directed into a shaft, so maybe look up the secound room.
In general we recomend this place a lot.
