The apartment is nice and comfortable, even nicer than the pictures, and in an excellent location.
Other than that - we found the bed to be very uncomfortable, the water takes quite an effort to flush and we didn't have enough hot water to fill the bathtub, which has no curtain so you can expect a wet bathroom through your stay.
We personally encountered communication problems with the hosts who proved unresponsive until a week before our arrival resulting in booking an extra night at a hotel because late check-in arrangements weren't handled.
