We stayed in Feb 2018 for two nights. The place was great - really easy to check in & out, very helpful and clear instructions from Guillermo. It was in an ideal location for us - close to some nice places to eat and drink, close to Chapultepec Park - and, although could hear street noise etc. in the flat, it was nothing more than you might expect from staying in a big city, and the streets surrounding the block felt actually relatively low on traffic. Guillermo was very quick to respond to any questions we had, and was super helpful in letting us keep our bags there all day after check out. We also loved the pool!
