We had an amazing time at Edwin's studio, where we spent 5 nights.
Extremely close to the Poble Sec metro station, the location is ideal for being a tourist in the city -- Las Ramblas, Montjuic, Gothic Quarter and the beach are all just a short walk or a few train stops away. The room was equipped with fantastic suggestions for places to visit and eat.
Edwin's studio should really be called a one-bedroom apartment. It's really spacious and extremely functional.
We had a lovely time and will recommend the Airbnb to all our friends.
