Communication was very easy, and very kind person.
Space is big considering the price.
Just to share the info, this flat is second floor of an apartment, which has separate entrance, and usually connected. So basically you can easily hear downstairs or one can easily hear you. And there is a cat living inside, so even cleaning with vacuum it is impossible to be without the cat hairs.
So for those who seek absolute privacy and having allergy with cat, I would not recommend the flat.
