In the end I enjoyed my stay at Adrians place. If you are looking for a personal connection with the owner, this is not for you. Adrians place is more like a luxury hostal and he is never there. It is managed by 2 wonderfull women a who really take good care of you if you let them. They are the cleaning ladies and if they like you, they will do anything for you, like inviting you to share their breakfast. Maro is the manager and he is almost always available and very helpful. The rooms are rather small and minimalist but nice, not all the at same level of quality, so be carefull how you choose. I had one without bathroom and then switched to one with bathroom. Both were nice, with nice beds and very clean. I would chose a room with bathroom for my next visit.
The kitchen is minimal but it works if yo do very simple meals. The common terrace is agreable and you meet people there at any time of the day, just like in a hostal. The location is perfect. You are close to Condesa and Polanco, 2 of the most interesting areas in Mexico city.
At first I was a little put off by the place, not sure why. Then it grew on me and in the end, with the motherly love of the ladies that take care of the place, I relaxed into it and enjoyed my stay. Recommended, with caution.
