Maria's airbnb is very stylish and clean. Located in Roma Norte, it's located close to Roma Norte and La Boheme coffee/pastry shop (obsessed with them...such a good location for daily breakfast). The apartment has a rooftop pool with a great view, and all the staff in the building are extremely friendly and helpful.
It's close enough to the city center (about 7 mins to Reforma 222), and walking distance to a lot of boutiques and shops in Roma Norte.
Maria and Angel have been very helpful with the checking in process, and extremely accommodating. Would definitely recommend.
