This is a great deal! Good location close to metro stop and great restaurants in Roma Norte. Please note that you will have to personally meet with the host to pick up and drop off keys. This will require extra communication about arrival and departures times, and, potentially, extra fees if arriving or leaving during odd hours. However, Guadalupe is an accommodating and communicative host, so this was not an issue, more like an extra step to plan.
Apartment is secure with gated entry.
We felt comfortable and had plenty of space. I recommend this stay.
