Great place about 10 mins walk from La Rambla. It's a lively neighborhood with two popular bars just downstairs. Aga did warn us about possible issues with the noise but we didn't have any problems sleeping. She also warned us about the multiple flights of stairs required to get up to the apartment. Getting a little bit of exercise after consuming all the delicious Spanish food wasn't all that bad though.
Aga was very friendly and greeted us when we checked in. She arranged a taxi from the airport for us, gave us a list of restaurant suggestions, and even provided us with new bed sheets.
