Luis reached out on Whats App and was very communicative ahead of our arrival which was helpful. He even met us at the door to let us in and showed me how to work the somewhat curious lock. If you arrive by car, you'll notice there's a lot of foot traffic around the apartment and a lot of restaurants. At first, it seems like maybe not the best area, but the more time we spent there we realized how wrong we were. It's located very close to the Metro and some of the major sites. There are a few spots along the street that are great for a drink and tapas, including a pub that owns a Senagalese store across the street as the area seemed a bit like Madrid's Little Senegal.
The apartment was clean and Luis showed me how to work the washing machine and where everything in the kitchen was during check-in. Be prepared to hang your clothes to dry as one cycle didn't get the job done. The street is a bit noisy late at night, but nothing too loud. Loved our stay!
