Pros:
Easy check-in, good communication with the host - he is really responsive, the apartment is close to some underground stations (although the 2 closest stations were closed during most of our stay).
Cons:
The shower easily gets really wet and not enough towels are supplied, so please be aware of it.
The hot water pressure rise and fall irregularly in number or amount.
No closet in the apartment, we took 5 nights at the apartment and we really hated living with our luggage open. it was a major inconvenience.
The flat could be cleaner - especially the kitchen.
