Flat is very well located (near main station, opera house yet peaceful), well connected (walk/bus/tram) & well equiped/maintained.
Building is not so well maintained (paint, common doors. Not big issue).
Easy Check-in/out. Fast/Clear communication with host.
Whole experience as good as expected.
I would highlight heating system (very important for us visiting from the tropics and with -15°C outside). It allowed a comfortable stay (much better than other flats we have used before)
I would certainly stay again.
