Communication is excellent! Giraffa was incredibly fast at responding, and every message that I sent she responded within a few minutes.
The apartment is really nice. We also found a binder with a lot of super helpful local tips (in many languages).
The location is great. It's within minutes (walking) of everything most people will be visiting, and the street is very quiet.
The only hiccup that we had was that we ran out of hot water one morning, but Giraffa was very responsive and even came to the apartment that same day to check on it.
