The location is safe and very convenient, with lots of shops for different types of food, supermarkets, even telecom shops to get a local SIM card. It is literally a stone's throw from the bus stop and metro station. The thing to note is that the metro station does not have elevators/escalators (as at May 2019). However, one can always take the bus to another station with handicap access.
Josefina and her family made me feel welcomed immediately. I really enjoyed my week's stay with her and will not hesitate to stay again.
