Pros: The view from the appartment is really nice and modern. The location is perfect. You can enter any time without bothering/waiting for the owner.
Cons: The appartment itself is really small so beware if you need space. There is a bit of noise from the airvent and/or the fridge which might disturb your sleep if you are sensitive. If you have problems with going up many flights of staircase with your luggage be carefull.
