This is a great place, newly renovated and quite modern.
Our host Antonio was not only very kind but also spent a lot of time with us explaining things to do and we also discussed Spanish history. He also helped us with early check-in.
The place is close to two metro stations with Plaza Espana only a few minutes away which hosts 3 train lines. We used one of them to go to Santiago Bernabeu stadium.
Only thing to consider with this place is that it is a 4 floor walk-up (on the 3rd floor), so if you have any health issues or very heavy bags, the initial and final baggage move can be hard. The host has plans to install elevators soon.
Overall we had a great stay and meetings Antonio was very pleasant. I recommend this place.
