This place offers extraordinarily value for the price! It's got very modern furnishing, it's a mere 15-20mins away from Madrid's main attractions, and the host is very responsive and considerate with any requests you may have. It's in a working class neighborhood, so the surroundings can seem a bit rough on the edges, yet it's super safe and has all the amenities you need (groceries, gym, pharmacy, public transport, restaurants...) so not really an area of concern.
100% recommended if you're looking for an uncompromising stay in Madrid that doesn't break the bank!
