Pretty basic apartment with 3 bedrooms and two bathrooms (both with shower and toilet) and a small kitchen. Located right above the Monumental metro station which was a great plus since we moved around using public transport while in BCN.
Noises from the hallway and street were really noisy and interrupted our sleep in the apartment, so I wouldn't recommend this place if you are a light sleeper.
The check-in and the whole key-in-your-phone was great, and I'd love to see more AirBNB hosts use it.
We had 2 power blackouts on our one-week stay, so I wouldn't recommend using the fridge to anything else than cooling your beverages.
The host answered to our questions quickly. Pretty good AC.
