I stayed at Rosario/Diana's place for almost three weeks. The apartment had all the amenities described and was a really functional and comfortable place to stay for this length of time. It is well kept and clean. The area is not immediately close to downtown, but the city is very walkable and the neighbourhood is particularly nice to walk around; all convenient markets/pharmacy and a few restaurants nearby while public transport is immediately accessible. The neighbourhood also felt very safe, even later into the evening. I highly recommend.
