Sophia provided us with fantastic support during the stay! The host is responsive and helpful. They are even replying not in working time regardless of the topic of the question.
I was working from the place, and I should mention the quality of the WiFi. It has a 200Mbit download and around 30 Mbit upload speed. The only cons for working was a huge window in the main room without a way to escape from the direct sun beams unless you moved to the couch or waited for 2-3h the sun to go away. It is tough to work when the sun goes directly into your eyes or the laptop's screen.
The place is a bit loud because of the thin walls. We were hearing even neighbors' steps inside his apartment. It's so loud that it feels like somebody is walking into your room. We thought we had left the door open a couple of times, and somebody got in. The children's crying also woke us up a few times. Unfortunately, these walls have excellent acoustics.
The kitchen is missing the spatula for frying in a pan. It was quite a surprise because the pan has Teflon coverage (easy to scratch).
Regardless of all these tiny issues, the place was great, and we enjoyed our stay of one week!
