My mom live alone, 10 minutes walking distance from entry #2 of PUCAMM in her own apartment. She used to rent a bedroom but she stop doing this as she had a bad experience with a crazy Dominican girl. The neighborhood is not nice at all but the apartment is in good location as it is right in front of CODIA ( Colegio Dominicano de ingenieros y agrimensores ) at Av. Estrella Sadhala La Villa Olimpica.
I'm willing she find a serious person to live with her. You know she sleeping alone in this apartment, the place is safe, they have a security guy in the parking lot who takes care of the cars and of the stairs of the building at night, I installed metal doors and metal fens the week before to I moved to the Us but she is a old lady and may get sick one night and she won't have a person to ask for help ( I'm only child).
She is still working so you will be by your self in the house from 7:00 am to 7:00 pm as she goes to visit her sister every day after work. If you are interested PM and will talk to her to see what she say.
