We really liked the apartment, it had everything we needed, it was very clean and the staff were kind, helpful and quick to respond. Having a laundry center in the building made things better for us since we were there for a week. The terrace is a plus, lovely area with wifi, clean and with a great view of the city, particularly at night.
It is very well located in downtown Mexico City, just 3 blocks away from the zocalo with police officers in every corner at night, making it great for night walks. Downtown Mexico City is a very busy area, so expect street noise which starts early in the morning when the businesses open, we were able to cope with it but if you are a light sleeper it may wake you up. The building itself is quiet though, we couldn't hear the neighbors.
We definitely recommend it and plan to come back.
