On the positive side, the location is superb and Jeff and housekeeper Rosa are nice hosts. Both reacted promptly and cared about how fared during our stay.
On the negative side, when we checked-in, we did have to clean up the whole apartment and especially the kitchen, which still had food and drink leftovers from the previous guest. There is also only one small electric heater in the main room and the main heater there did not work, so it does get chilly in the colder months.
Given the rent, we did not expect both of these issues and a few further minor ones (such as noise and occasional interruptions of the internet service), but, since the area is super expensive anyway, we can't really tell if such a value for money is normal.
