We met Ramon's friend just outside the apartment it was very easy to find, in the centre of Madrid. The apartment had most of the necessities, we had to pick up some basics like sugar and laundry powder from the nearby minimart. The bedrooms were reasonably sized and well lit with a small ish wardrobe.
The best thing about the apartment was that it was smack bang in the middle of everything you want to visit and only 5 minute walk to one of the major subway stations SOL. 15 mins from bull fighting and 20 min walk to the palace.
Good for families or bunch of friends exploring Spain.
The host was super helpful and friendly even when we ran into trouble getting into the building! Such an easy transaction and they really catered to our needs when we asked if we can store our luggage until our flight at night.
Thanks!
