Overall, had a positive experience. More details about pros and cons below:
Pros:
* High responsiveness to problems in the apartment or requests - from quick fixes to providing fans and heaters when needed. Very professional customer service.
* Space of the apartment is nice, including the unique interior design. The balcony area is quite big and comfortable.
* Heater works well, was important during some cold nights.
* Dishwasher is great, never needed to rewash.
Cons:
* Wifi is very bad, despite attempts by the owners to fix it. Does not fit remote work or learning - video chats don't work well.
* In specific "rush hours" there will not be hot water in the shower, since multiple people in the building are taking a shower at the same time.
* Washing machine is quite noisy.
* Location is central (close to everything), but at the same time a lot of noise is coming from the streets, especially at night, and sometimes you can feel some shaking from the metro train passing below. Closeness to a church doesn't help either (bells ringing).
* Some areas in the apartment, like behind the closet in the bedroom, were quite dusty.
* Isolation of the apartment could improve. we could feel cold wind coming from the windows even when they were closed.
