The apartment is great! Well decorated, spacious, has a nespresso machine, the beds are very confortable.
The communication with Sergio was perfect, he let us leave the luggage after check out and pick it up later. The apartment is on a ground floor so no stairs! :)
There is a nice restaurant in the corner, Viuda de Vacas with amazing Spanish food.
15 min walking from sol at a slow pace. Metro is 5 minutes walk.
Would definitely stay at Sergio's again.
