Ernesto's place was a great spot to stay for a month in Mexico city. the apartment is small but has everything you need and is really close to many restaurants and bars and everything you need in Roma/Condesa. The apartment gets plenty of light which was great as I was working remotely during the week, wifi connection was also strong. There is some noise from outside and the other apartments which I was a little worried about on my first night as I'm a light sleeper. But I had no problems at all sleeping and I think you just have to expect outside noise in Mexico city. weekly cleaning was also a great additional benefit
