The place is extremely clean and well located. You should have no problem accommodating 4 people in this charming apartment. AC and WIFI worked fine. Within walking distance to The Ramblas and Passeo de Gracia.
Be aware that the host took a few days and a call from Airbnb to respond to several messages i sent just days before check in. Even though we had no issues with the reservation at some point i couldn't help to worry about finding a place to stay at the last minute.
