Luis apartment is great. The location is in a safe neighborhood that allows you to walk around Rome Norte. The cafes/bars/restaurants there are no more that 10-15 minutes away on foot. The apartment has all you may need, from bath to kitchen amenities. Luis even had a few snacks and beers waiting for me!
Communicating with Luis was really easy. He responded to my messages always on time, he let me check in earlier than the agreed checkin.
All in all, I enjoyed my stay there and I would go back.
