Everything five stars. The location is great - in the middle of Centro Historico. Many restaurant and tourist sights nearby. We felt pretty safe. The apartment was very clean and had everything we needed. Some notes to indicate how great the host was:
1. Some of our group arrived 7AM in the morning. The doorman and host were able to take their luggage and replied to our message quickly.
2. We asked for an extra blanket at 11PM and Alice sent it to us in 5 minutes.
3. The host recommended us a private driver to take us to Teohuacan. They came on time, the cars were clean, the drivers were nice and very responsible - they waited for us for 5 hours without having any food. We felt bad for them so we tipped him and applogized. They sent us a small gift at the end of trip. The price was very reasonable for what they provided.
Would recommend this place to anyone visiting Mexico City.
