Highly recommended! First of all, Andrea was a great host. Responsive, friendly, and accommodating.
The apartment is perfect for a couple. It's in great condition, is very comfortable, and it has AC! The apartment is also in a great location. It's a short walk to some points of interest such as La Latina and Palacio Real, and also close to bus and metro stations. If you have a car, there is free street parking nearby (just a few minutes walk), but you really don't need one to move around.
Next time I go to Madrid I will be staying here again.
