First of all, Edwin's flat is absolutely beautiful and so tastefully arranged, I wish we could have spent more time there! Check in was great, and we so appreciate that Sylvia was accommodating and understanding when our train was delayed and we had to check in late. She provided a number of local recommendations and gave us a good tip on a TMB bus to take to the airport (the 46 in case you're interested).
The location is wonderful, steps away from great restaurants, tapas bars (Quimet & Quimet was our favorite), and an awesome bakery (La Fabrique). It is also very easy to access the city center and Montjuic. We would have liked to try more places, but our stay was too short. Despite being close to bars and restaurants, the flat itself is on a very quiet street, we slept so well! The bed was very comfortable, and the flat is the perfect size for two people. The bathroom is basic, but perfectly adequate (good hot water).
Overall, we could not have asked for a better stay and highly recommend Edwin's flat.
