First the Good:
I never met Kevin, but he was personable and responsive.
Check-in was easy.
The flat is close to a metro station.
The apartment is nicely decorated, wit high ceilings and good windows so the room is lovely and bright.
Good water pressure and hot water.
Good WiFi.
Next the: "Is what it is"
The flat is on the 6th floor. It takes 120 steps to get up to the flat. I pride myself with being in excellent shape, and even so, there was no single time that I made it to the flat without being out of breath. And if you ever forget something in your flat and realize it when leaving the building, chances are you won't go back for it. One night, I had planned to go to the market to get some supplies, but I couldn't face the climb down and up. At the end of 5 days, my knees were significantly inflamed.
The bed is in the loft - and while the mattress is comfortable, the area is claustrophobic and hot. I was visiting during a particularly warm period and sleeping in the loft was not possible for me, so I slept on the sofa (not ideal).
There is no television.
The flat is full of the tenant's things. As such the closets are full of clothing and the refrigerator/freezer is full of someone else's food.
The bathroom is small (basically 1.5 square meters) and the plumbing is bizarrely loud.
The flat has no air conditioning as such, it makes sense to keep the windows open; however, the neighbors can be loud and chatty.
Finally, the "Not So Good"
Linens are less than luxurious and the towel was positively stiff and sand-paper like.
