This place was a real mixed bag for us, so I'd like to leave a thorough review.
My family (wife, baby daughter, and I) stayed here for a bit over two months.
Communication:
The communication after making the reservation was terrible: About a week before our stay was going to commence, we received a message from the host saying there was some problem with our booking, not stating any details. In the following days, we sent several messages - which were ignored - and called by phone several times, where each time we were promised a callback, which never occurred. Only after involving Airbnb's support - who presumably put some pressure on the host - were we finally told that the problem was that price at which we had booked was lower than had been intended by the host. The price was indeed a little lower than comparable places in the same area, but still considerably higher than, for example, what we're paying for our own apartment in one of the nicest neighbourhoods of Berlin/Germany. So since we did have the confirmed booking, we decided to go ahead and stay at this place.
Check-in was very good. Patricio was very friendly and helpful. He even organised a tub for us so we could bathe our baby daughter. Whenever we needed something during our stay, it was easy to get in touch with Patricio, who most of the time responded promptly.
Location and safety:
The location is great. Roma Norte is one of the nicest neighbourhoods in the city, with many good restaurants and bars in walking distance The apartment was quiet most of the time. About one night per week, there was loud music from a bar on the opposite side of the street, which didn't bother us too much.
We always felt safe. The apartment has a door, a steel gate in front of it, and many locks. Since the place is on the first floor, one can quickly escape in case of earthquake. The public earthquake alarm is audible inside the apartment (as long as one doesn't make too much noise oneself). We found it reasonably easy to make the place child-safe.
Cleanliness:
We didn't find the place to be particularly clean. Especially the carpets and the windows could use a proper cleaning. Since even the dining area had a carpet floor, we struggled a bit to keep it clean despite our one-year-old's eating habits.
A nice bonus was that cleaning was included, which we took advantage of once per week. The cleaning ladies were very friendly and efficient.
If you need garbage to be taken out while the cleaning crew is not around, which we did often (diapers), you need to hand it to the friendly caretaker, whom you'll have to pay a tip (part of which he'll give to garbage men, presumably).
Aesthetics and comfort:
The apartment is indeed very spacious: three large bedrooms, a long corridor, two small full bathrooms, small kitched, and a large living/dining room.
It's very ovbious that the place used to be an office. All floors are covered in grey carpet, and there are power outlets in the floors. Most of the lamps emit a bright, cold light. The furniture has seen better days; some of it had small damages, and most of it seemed to be lovelessly picked out and arranged. There were a few plants in the apartment, which had not been taken care of well; some of them were dying when we moved in. We liked the art pieces on the walls. The bathrooms and the kitchen could use a refresh. The view out of the windows is obstructed by an ugly green fence. There's a good amount of daylight coming in through the windows.
The bedrooms do not get particularly dark at night, which bothered my wife, who is a light sleeper. I found the beds very comfortable. My wife found them too soft.
We found the kitchen small and badly equipped. Many essentials were missing. The oven was not operable and the stove was slanted, which was annoying when trying to fry something. The coffee machine uses plastic capsules, which produce good coffee, but are a nightmare ecologically and economically. There were a toaster and a microwave.
Water pressure was very good by Mexico City standards.
There was no washing machine. We used a laundry service some 50 metres from the apartment, which cost 35 MXN/kg for washing and drying, and which produced good results.
In summary:
We thought the place had a lot of potential. Given its size and location, with a little bit of love (new flooring, furniture, kitchen) it could be truly amazing! As it was, we would not choose it again for any long-term stay. We imagine, however, that for short-term visitors who don't cook a lot but instead want to sample the great food and nightlife in the neighbourhood, it could be just right.
