Katia is a very friendly and responsive host. It was easy to work with her throughout the booking process and during our stay. The apartment is conveniently located to two different metro lines, and has some lovely walking routes with great parks nearby. We had everything we needed, both in terms of sleeping and bathing, as well as kitchen needs. The apartment is generally a good value.
The only challenge we faced was neighbor noise, in particular one neighbor below who would watch the TV loudly with her windows open (and sometimes shout at the TV), and another neighbor who played music loudly sometimes. Thankfully, these noises were during the day (late morning to mid afternoon), so if you are out and about it shouldn't be a big issue. However, if you are planning late nights (for music or something) and intending to sleep in, the sounds may make that more difficult.
