Make sure you get detailed instructions on how to get the keys (3) from the lockbox hanging on a chain outside the building . And detailed instructions on how to find the room. You get keys for the front door, the back elevator, the inside room.
This is a private 5 room apartment with 2 bathrooms and a kitchen. The elevator takes you to the stairs where you then go down or up one flight. I never understood which floor this was on. There is a small tag by the apartment with Lilians name. I think it is on the 4th floor? Lilian does not live there but is readily available by telephone. And she magically appears when you call from somewhere about 15 minutes away.
