We had 3 days in Madrid. The apartment is great, just a little bit loud sometimes in the evening but it wasn’t a problem for us. There is everything you need in it and Dan is there for you if you need informations or help. Very well located near Atocha station (15min by walk), the city center (15 min by walk) and just next a little market where you can find fresh products. There are also a Lidl (5 min by walk) or a Carrefour (10 min by walk). I recommend this place.
