Positive: very supportive and friendly host, very good location, beautiful modern apartment, comfortable bed, many toiletries in the bathroom, fully equipped kitchen.
Negative: no dishwasher (not all the dishes were clean), no sharp knives, very loud outside on the weekend, check-in with the owner instead of a key box, no international TV channels, very steep narrow stairs to the 2nd floor (super uncomfortable if you have a big suitcase).
