Sabine was always available before and during stay. The location is perfect, close to central city and airport. Easy tram and train to airport. But Review getting off tram 17 at stop to airport. You need separate ticket for train and the kiosk to purchase ticket there wasn’t working. I would buy ahead of time. The locals were very willing to help. One helped me find another kiosk and stayed till I got into train station.
The apt was nice, location safe and easy to get around, seems to be older neighborhood being renovated for hipsters. Three flights of narrow stairs to apt so no heavy suitcases or too much partying. ;-)
