We stayed at Justine’s place for a 5 days and I can say it's a good price/quality combination. Good location, a supermarket in the building, buss stop in 1 min, 15 min walk to the museum of modern art. Apartments has everything you need as well as useful local tips. During our visit I communicated with Justine’s co-host and can say he was answering quickly, explanations was understandable and was ready to help in case.
