We stayed here for 3 months. Big one bedroom apartment one level up from street. Elevator in building but we took stairs every time. No doorman. Lots of natural light. I work remotely and internet wifi was very fast. Two of us were able to stream movies and use zoom or teams without any problems. Kitchen is smaller but we went out to eat all the time since food is so cheap here. Building and apartment are a little dated but everything works well and is in a great location. Noise was never an issue for us and building felt quiet. Yes sometimes you can hear people walking around upstairs or people talking in hallway but nothing that was bothersome. No loud bars or clubs nearby so able to sleep really well.
The location is amazing. One block off Reforma near El Angel on a quiet street with little traffic next to US Embassy so felt very safe. Several street tacos and fruit stands outside front door. Tons of bars and restaurants only a few blocks from house. Walmart Express within 5 minutes of house for groceries. Able to walk to Juarez, Reforma, Roma Nte, Condessa and Chapultepec Park. You could even walk to Historic Center but the Metrobus runs up and down Reforma all day and only costs about 5 pesos. The closest metro stop is Insurgentes which is 10 minutes walking. We would definitely stay here again!
