The stay was great. The apartment is super central, so I would give 6 stars for location, if that was possible.
The apartment is very convenient for two and very well organized. Highly recommend. There is a supermarket just a block away and a cool jazz club 70 meters from the flat. We went everywhere by foot and didn't need the public transportation at all (except to and from the airport, of course:). Yulia was very kind and cooperative.
