The location is absolutely amazing, it's right in the middle of the main shopping street (Ermou) and allows easy walking distance to the main areas of the city.
The apartment is spacious, clean and comfortable and we had a really nice stay there as a family. The hosts are super responsive and will reply within minutes to nearly any question you have and they are friendly and nice.
Personally I would surely stay there again on my next visit to the city. A+++
