I only have great things to say about Andrei and Alina's flat! We were very well received by Alina which gave us a list on Google Maps of really great places to eat in the city. The flat was super clean, organized, and very well equipped! We stayed a whole month and had everything we needed. We had friends with a baby come stay with us a few days for a super reasonable extra fee and they provided a crib and a feeding chair. About the localization, the flat is really close to really cool bars and restaurants, close to Barceloneta beach, close to Las Ramblas and very quick walk to metro stations. We loved the experience and miss the flat already! 100% recommend :) Side note: hosts were super friendly and also responded quickly during the whole stay!
