We stayed in Andreis apartment for four days. Check-in was easy, as a friend of Andrei was welcoming us even late in the evening. The apartment is well located right between Poble Sec and Sant Antoni - you can literally walk everywhere from there. The flat itself is small, but cozy. It can be a bit chilly in the winter months, but there are heaters available to keep warm. Everything is arranged very professionally, so if you want to go for a safe trip, I'd definitely recommend Andreis apartment.
