The flat is spacious, clean and centrally located. I wouldn't recommend it with kids though, as the neighborhood is not very neat and walking there in the dark with kids doesn't feel right.
Nestor and Chris were ultimately devoted to give us the best stay. Kuddos to them for the unconditional effort. Unfortunately we didn't have a lot of luck during our stay. There were problems with the hot water the first day (next day fixed). And we also had to experience finding some dead/dying cockroaches from time to time because of a previous infestation, which was handled very professionally of course.
If your a gang of six young people, I'd say, this is the best place to stay. If you're a family with small kids, maybe there's something better Nestor and Chris can offer somewhere else in the city?
