Cristina's place is impeccable and has an amazing location as well, since its near the first stop of the ferry boat from the airport. this made it a very quick and easy check in/out process for us. Many warned about the amount of stairs to get to the apartment, while it is significant, I belief the view of a canal from a high rise are is well worth the effort. thou people with mobility issues would find it quite challenging.
All the amenities where great, we did find that having a washing machine available made it easy for us to have some fresh clothes to wear by the end of the trip.
My favorite thing was to get into the ritual of cooking some breakfast and using the Nespresso Machine for a quick coffee while overlooking the canal from the bedroom. simply magical :).
