Positives:
Location - the location of Maria's AirBnB was fantastic. It's extremely central, is in a safe neighborhood, and is walkable to a lot of restaurants, parks, and markets.
Spacious - the apartment was spacious and Maria left us with lots of spare linens. You also have access to a laundry machine, which is always helpful.
Accommodating to irregular checkin/out times - as mentioned below, we arrived in Mexico City in the middle of the night, but Maria provided us instructions on how to get in. Additionally, when our flight was delayed, she contacted us to make sure everything was ok. On the day of checkout, she was accommodating to a late checkout and let us leave our luggage in the house a few hours past regular checkout time.
Negatives:
Beds/Couches - the sleeping situation allows for three guests. There is one full/queen bed, which is extremely hard and left me feeling sore for the entire duration of our stay. There is also a couch in the living room, but it's not a pullout couch as initially expected and only fits one person. The main problem with the couch is that it is two separate pieces and they slide apart while sleeping on it. Additionally, the apartment is on the ground floor and has glass doors that open to the shared courtyard. This allows for lots of natural light, however, the curtains do not cover the width of the doors making it feel like you have a lack of privacy, especially in the evenings.
Water temperature/shower head - the water temperature in the bathroom and kitchen was very difficult to control, going from cold to boiling hot in a matter of seconds. Additionally, the shower head was at times very painful due to the temperature as well as the pressure.
Responsiveness - We contacted Maria prior to our trip to ask for directions to get into the AirBnB as our flights were landing in the middle of the night. She was very slow to respond and didn't get in touch with us until only a few days prior to our trip. However, once she responded, she left us with valuable information and was readily available throughout our stay.
Smell throughout apartment - We noticed a slight smell of mildew in the bedroom and the kitchen. We were able to air out the bedroom by leaving the door open, however the smell in the kitchen still lingered through the week.
