Very friendly and responsive host. Unfortunately have to take a star away for neighbors that were fairly loud all day long (most prominently a screaming child). On the plus side the bedroom was mostly quiet so we were able to sleep ok. For working, the kitchen was sufficient, even with the noise. WiFi performance for work was mostly ok and reliable.
Flat was well equipped with basics in the kitchen present (salt, sugar, coffee etc).
Flat location was okayish. The neighborhood is fine, but you still do take some time to get to the center. This will be improved in a couple years when the C metro line gets extended.
Overall nice place for shorter visits probably. Less so for long stays (due to noise).
