Great 7-day stay with my girlfriend here. Mantoli is a lovely person, she welcomed us and explained the details of our stay really well.
The location is really good as you have the subway really close. The microwave, the little fridge and the private half bathroom was really useful for us. The main light bulb was not working but they changed it the next day. The main bathroom is good and clean.
Didn't get to meet Andre but the communication with him was fluent.
The only but I see is the bed, although is comfy, is really noisy and perhaps the sheets could be nicer. And, as Andre mentions in the description, the building is old, so don't expect any luxury on that part.
