This was our first time booking accommodation through airbnb and the experience couldn't be better. The rooms and the kitchen were just as on the pictures i.e. small but very functional and clean, air conditioner in both rooms included. There were more than enough sleeping places for a family of 4, the folding beds in the living room being quite comfy while occupying zero space during the day . Renan also provided a baby crib per our request. The location was perfect some 200 meters from Callao subway station on Gran Via, a walking distance from most tourist attractions. Renan's colleague that welcomed us was very nice and helpful. A bottle of red wine plus a couple of beers and soft drinks in the fridge (free of charge) completed the picture.
If you are travelling with a baby stroller beware that there's no elevator so you'll need to drag if to the first floor (one flight of stairs).
