This is a really nice cozy stay in Madrid. The location is superb and the communication from Pilar was excellent. She’s a great, detailed host and the check in/check out process was smooth. There is a supermarket 15 seconds outside of the apartment, and a train station in a two-minute walk.
I can’t think of a specific “con” of this place. Tbh it was everything I needed/was looking for. What I will say is that as mentioned, it is a small place, but it does have everything you need and the if you select this place, it will be a pleasant stay.
