The pros: Very clean, great location, good beds, good heating, responsive and friendly hosts, generally quiet. The house has a great rooftop and view.
The cons: Feels like a big empty house and lacks warmth. The photos are accurate but doesn't capture the sterile feeling. The lighting upstairs is odd. Some noise from the adjoining townhouse in the master bedroom (could easily hear their TV) . Many other minor things not worth going into individually, but overall, left us with the impression that the house should just be on the market to be sold/rented rather than used as a guest house.
