positive:
the location is just perfect. metro and bus are just some footsteps away. a supermarket and a cute coffee shop are directly across the street. The building full with graffiti is actually a piece of street art.
the residence has two elevators.
check in and communication was really easy and fast.
the apartment is nicely decorated.
negative:
BLACK MOLD in every room, especially in the bedroom with the double bed. The owner must have tried to paint over the mold, but it came trough the color during our stay.
The flat only has the most essential items, so we had to buy a lot of stuff to live comfortably (e.g. soap, basic spices like salt and pepper, trashbags,...)
the two pots and pans were really small. we had to cook the same meal twice, so that 3 people could eat.
Conclusion:
if there wouldn't be mold, it would have been a perfect stay.
