Maria's place is in a great neighborhood. Very close to lots of good, hip, fun places to eat and drink. Also close to a number of parks and a grocery store. When we arrived there was some fruit, bread and tea for us which was very nice. The decor is nice and again the location is really great!
If you go in the winter it is pretty cold in the apartment. There is only one space heater so if you are in the living room or kitchen you need to have it right next to you. It works well for heating the bedroom while you sleep. If you are coming during the winter months bring some thick socks, pants and sweatshirts for when you are at the apartment. The apartment is also very damp so that adds to the cold feeling.
I would also recommend bringing earplugs for sleeping. This may be common in Mexico, but you can hear EVERYTHING in the apartment above you (phones, conversation, walking, chairs), there are cats that fight and pipes bang throughout the night. Did not usually sleep great.
Overall we liked the apartment because of the location and all the plants add a nice homey feeling.
