First, the positives. Jaime's place is very well located near Chapultepec Park, and the garden and house are lovely, like in the pictures. It is a safe and quiet neighborhood and Jaime was prompt and welcoming at check in. The bathroom was great.
Now for the negative. Our bedroom had a window which looked out on a small hallway at the back of the house, not onto the outside as you would expect. Neither the photos nor description of the room indicated this! There is therefore little ventilation or natural light in the room. Further, the bedroom is right next to the other guest room (both appear freshly constructed, and are very clean), with a super thin wall through which you can hear everything in the other room. The other guests' snoring was literally vibrating our bed (and coughing, phones ringing etc. as if in the same room).The bed was cheap and uncomfortable. The other photos of the house's main rooms are accurate but these spaces (except the kitchen table) are not accessible to guests and their doors remained locked. Essentially Jaime has built a tight two-bedroom hostel at the end of the upstairs hallway, divorced from the rest of the house.
As a couple on a short vacation to Mexico, and after sleeping very little on the second night (see above), unfortunately we checked out three days early to find an alternative accommodation. Jaime was out at the time (we left the key with the gardener) and he did later suggest by Airbnb DM that he could have switched our room. It did appear that there was a third room more in keeping with the house's character and spirit (and with a proper window), so maybe try to book this one during your trip.
