Great stay. Place was really spacious, and close to lots of bars, restaurants and public transport. Very central - you can walk to most major sights. Fairly quiet for such a buzzing area.
All the basics you might need were provided - coffee, sugar, detergents etc.
Great communication with Montse on check-in (thanks for the clear directions) and no problems during our stay so no need to contact her again.
Only notable is the stairs! The apartment is on floor 5, so would not be suitable for some.
