This apartment is only a short 10-15 minute walk to the center of downtown Madrid and 20 minutes from the Atocha station. It was extremely accessible and easy to find. The apartment itself was very comfortable and cozy; felt great to want to come back to the apartment to rest after romping around town all day. The shower was a little small for my 6'2 partner, and we weren't able to take showers one after another (due to a smaller heating tank), but that's the only small "issue" we found! Definitely recommend staying at Natalia and Roberto's place while in Madrid!
