Great communication with Alvaro, who also kindly let us drop off our luggage as our flight arrived early.
The apartment is in a quiet neighbourhood, 3-5 minutes walk to La Latina metro station, with a couple of minimarts along the way for daily supplies. Good heater that kept us nice and warm.
The building itself is located on a slope, but it was manageable even with our luggage. After a short flight of steps, there is an elevator to the floor of the apartment is.
