We stayed at Alejandro's place for 11 days and we loved it! Alejandro is a great host. He was very helpful during our whole stay. He was also very thoughtful and flexible when it came to our (quite late and quite early) check-in and check-out schedules.
Location couldn't be better. The house is located right at the heart of "La Roma", one of the trendiest neighbourhoods in Mexico City. You can find great coffee shops, bars and restaurants all over the place. It is also within walking distance to other cool neighbourhoods, such as Condesa or La Juárez, and just a short ride away from Downtown. It's also well connected as there are Subway, Metrobus and Ecobici (public bikes) stations nearby.
The house is beautifully decorated and very clean. It allows a lot of light in the common areas. The kitchen is well equipped, in case you feel like cooking!
We stayed in room #10. The room is very comfortable and spacious. It has a double bed, a mini-fridge, a desk, and enough storage room for clothes. It has a big window, allowing for ventilation and natural light (not all rooms have windows). We had to share the bathroom but we didn't mind as it was always clean. There is a funny smell coming out from the bathroom's strainer (upstairs) and it might get stinky from time to time, but that has nothing to do with the cleanliness of the place. It's a particular problem of the drainage system that affects some buildings in the neighbourhood. Nothing to worry about. :)
We also had the chance to meet the lovely cleaning lady, who helps Alejandro with the house. She is wonderful and extremely helpful.
We absolutely recommend Alejandro's place for your visit to Mexico City.
