Had a great stay here as the location was very central so we could walk everywhere or get the Metro from our apartment. We were given a nice welcome and were delighted that we could check-in early after our early morning flight. All the facilities in the room were explained to us upon arrival as well as where the local supermarkets were. All services and facilities listed as correct, all modern and super clean.
The only downside was the sound-proofing of the apartment wasn't great, we could hear everything that was going on in the foyer, noises from the apartment above and construction work on an apartment across the street, despite the apartment not being on the street-side of the building, which woke us up or kept us awake.
This is only minor though, and I would without hesitation recommend that anyone and everyone should stay here as the hosts are perfectly kind and helpful, and the apartment is clean, functional and a welcome retreat from the streets of Madrid.
