Absolutely perfectly positioned in downtown Madrid (across the road from the food & Tapas market) and a short stroll to Plaza Mayor and other tourist sights.
With chocolates spread around and breakfast foods provided this small (you need to crawl into the comfortable upstairs bed) but fully appointed apartment was quiet (facing away from the main street) and had good privacy and security.
We booked with almost instant feedback and Luz was extremely helpful with directions (in english). On arrival Luz was able to meet us with only 15 minutes notice which we actually did not expect!
