Great location. Very friendly and communicative host. As others mentioned, there are many flights of stairs required to get access to the unit. Sufficiently comfortable beds and adequate water pressure for the shower.
The floorplan of the unit appears to be designed as a hostel/shared apartment space, so there are separate bedrooms and bathrooms with shared kitchen/hallway area. This makes for decent privacy when staying with a group.
There appears to be some issues with the plumbing, as there is a sour smell permeating the apartment. However, the shower, toilets, etc. were all in working order as far as we could tell.
