Can't beat the location of Maga's apartment. Right in the heart of the Gothic Quarter and walking distance to countless shops, restaurants, and bars.
Maga was extremely communicative and we had no issues at all getting keys, checking in, or checking out. She was even nice enough to let us leave our bags in the apartment after check-in, until our flight in the afternoon.
I would definitely recommend this apartment if you're looking to be in the hear of Barcelona's nightlife!
