Sergio was a great host, letting us come an hour early while he was still cleaning from the previous guest. We were exhausted from traveling and grateful for this. The flat itself is typical except that one exciting feature was artwork from his mother on his walls- she was very talented and it is touching for the host to share this with us.
The neighborhood of Lavapies, unlike nearby neighborhoods, and this apartment in particular, is located on steep roads. This is a hassle with luggage, but distances are short in this area of Madrid because there is a lot of great things within a short walk - Prado, Reina Sofia, San Fransisco Market, Atocha Station (for the national RENFE train network), and of course a metro station a couple blocks away.
I leave a five-star review but I would like readers to know that the apartment itself is located four flights up and there is no elevator.
