Location, location, location! You're close to all the best eats in Roma Norte (Rosetta, Panaderia Rosetta, Santo Hand Roll Bar, just to name a few) and Plaza Rio de Janeiro, which was a great spot to sit and people/dog-watch. As a solo female traveler, I felt very safe here. Luis was a great host, the building is beautiful (google "Casa de las Brujas" to learn about its history!), and the apartment was comfortable. Wifi was also perfect for working remotely for 2 weeks at 60+mbps. My only things to note was that the apartment does get very dark when it's cloudy outside or at night, and the shower pressure is light. If either of those bother you, maybe consider somewhere else, but I hope you don't! I would happily stay here again. Muchas gracias, Luis!
