Maria's place is a decent one. The La Condesa area is very posh and nice. You can just walk in the area in the evenings and have a good time. There are many eateries around this place hence you dont need to go far away. There is 7/11 right next door. So, thats very convenient.
Things to note:
1. This is a very old place. So, dont expect something that you get in a new place.
2. The washrooms are shared
3. The flooring is wooden and hence makes lot of creaking noise
Positives:
Maria, her son and grandson are wonderful people. They are always ready to help with any problem that you encounter. :)
