Minerva's place is clean and well-equipped. I read some previous reviews mentioning lack of toilet paper and AC but both were not issues as there was more than enough for my one month stay and a fan in the room. I stayed for a month, and it was walking distance to all there is to do in Roma Norte. The lighting is also great, and there is a tv in the bedroom.
Minerva is also an excellent host--one of the better ones I've had in Airbnb.
