We generally had a pleasant stay in Diana's apartment. She is a friendly and nice person. And her dog is very cute!
We had two small issues though - it turned out that there is only enough hot water for one shower of 5 min and then you have to wait for another hour. Not knowing that, we had to adjust when I was quite soaked from the rain. Short straw.
Check in could be improved, but nothing major really.
It is 20-25 min from City centre, but there are a park, church and few other things on the way, which makes the walk quite pleasant.
