Amazing location in a lovely and mostly quiet neighborhood. You have everything you could possibly want closeby including corner stores, a bakery, street food, shopping (Patriotismo) and a grocery store (Superama WTC, 10 minute walk). The Patriotismo metro station is about a 10 minute walk. The district is very safe and we felt comfortable walking around, no matter what time of the day. Condesa is a short 10-15 minute walk away.
The entrance hallway is always very clean. Neighbors are all families and are very friendly. A couple families have kids so this is not a place for having large groups of people for a party.
Place is suitable for a long-term stay. Internet is quick and reliable for the most part. The kitchen is equipped with everything you need and has a decent amount of counter space and storage. You can very comfortably live with 2 people here but I wouldn't suggest a 3rd guest if you are planning on staying for a long amount of time.
