I stayed in Evgeny's apartment for one month.
Pros: very clean, great location just off the river in new town, public transportation close, quiet building, nice little balcony, safe area.
Cons: There is massive lump on one side of the mattress that I consider unsleepable. It didn't affect me because I was able to sleep on the unlumpy side. The building opposite is currently undergoing reconstruction which often begins as early as 06:00. For those who appreciate the Airbnb high level hosting experience, this apartment may not suit. Evgeny functions as an absentee landlord. He provides no instructional material about the equipment in the apartment, the building, the neighborhood, or Prague in general. He is slow to respond to questions/problems and seems disinterested in the guest's experience. In the month I was there, I never met him, and he never messaged to inquire about my well-being.
Overall, I enjoyed my stay, but I doubt I would return, and I would not recommend this apartment to other solo female travelers. It was a little too solo.
