I made a reservation at Ruzanna's for my mom (not for me). Her place was great- it's on a lovely street in a beautiful, quiet neighborhood. My mom slept well and enjoyed her time there. Ruzanna was very helpful and responsive - when there was a problem with the shower, she came in right away and fixed it.
One thing to note is that the apartment is a good-sized kitchen and large bedroom. There's no proper living room. Other than that, it's a charming and peaceful place to stay.
