Highly recommended!
The place was clean & tidy with room service similar to a hotel. The host, Felipe, is friendly and is an accommodating person and is most responsive. This is perfect if you are wanting to know what it feels like being in a royal family from back in the days.
A few minutes walk from Royal Palace of Madrid and an even shorter walk to a train station for you to start your adventure. You’re also just less than 10 minutes walk from central Madrid with full of restaurants of your choosing.
You’re only about 35-40 minutes train ride to/from the airport or 20-25 minutes Uber drive.
