I've had a great time staying at Stepanka's place. All the instructions were clearly stated and professionally laid out, the check in (met in person) was fast and the apartment was very clean and well equipped - towels, clean bed sheets, soap, hair dryer, cutlery, kitchen utensils and appliances in good working order. Temperature inside was acceptable.
Exterior gate stays locked and the hallways are illuminated with sensor lights so it feels safe at pretty much any hour. Long term tenants around, really quiet. I could sleep with no issues.
Tram and bus lines that go to the attractions in the city center in a few minutes are nearby - just note that there's a fair bit of hill to go down to the tram or up back to the apartment building.
I would gladly come back given the opportunity.
