We had a lovely stay at Erick's place. He was prompt in responding to messages (and even came over when the TV was not working to fix it). The place is clean, airy, and feels hotel-like. We enjoyed a swim in the pool on premise and also enjoyed the large deck (which you can access via stairs by the pool). The security guards at the front were incredibly kind and the location felt quite safe. The neighborhood was also great - walkable to many great restaurants in Condesa, Roma Norte, and Hippodromo, close to the metro, and on a quieter street.
A tip for checking in for international travelers without internet service on their phone when abroad - walk to the apartment door and connect to the apartment WiFi to message Erick, receive further check-in instructions, and get the door code.
