Luis's place is located in a PERFECT location. You'll be located right in the middle of everything. Lots of food place around to choose and many activities and landmarks within 5 minute walking distance. The place is very spacious and had all the amenities we needed except a dryer. Only negative thing was that a few times I had to close the doors due to the smoke coming in from people downstairs. (That's NOT Luis's fault) In addition, be mindful, you'll be climbing lots of stair to get to the apartment. Not a big deal, except for when you arrive if you have lots of big and heavy luggage. Other than that, I definitely recommend this place to stay. If I ever return to Madrid, this will be my choice.
