We really enjoyed our time in Madrid as well as the apartment. It is really central to everything and we love the neighborhood. Easy to get to public transportation (taxi, bus, metro - La Latina station), and only a few minutes walk to Plaza Mayor, Puerta del Sol, Mercado de San Miguel and the Royal Palacio.
Lina, a friend of Laren who is helping us and providing us with the information is very easy to communicate with. Check-in and check-out also very easy and comfortable.
The apartment is very clean, bright and same as shown in the pictures, however, we were a bit distracted by the noise from outside/neighbors.
I would love to recommend this apartment.
