What an amazing place to stay in Madrid. Super close to tons of food and shopping, and a five minute walk from the metro made getting around the city super easy. The place itself was very clean and full of personal touches and amenities. My friend and I were able to enjoy our own sleeping areas.
As others have mentioned, there's no elevator, and it's really more like five flights of stairs to climb, so just keep that in mind with luggage. You get used to it after a day or so!
Overall, highly recommend!
