Plus: great location. Transits stops (train, busses) close by. Grocery stores close by (walking distance). Comfortable bed. Perfect size for two people. Good appliances in the kitchen.
Minuses: we had no warm water in the shower. When we got there the flat was dirty and we had to wait for the cleaning lady to get there and clean it. The couch is dirty, it has stains.
Constructive criticism for the owner: less is more, the flat has too many furniture pieces in the living room (in the living room only). Needs new couch covers or a new smaller couch.
Other than that the location is convenient.
