Olga's newly renovated apartment is spotlessly clean, tastefully decorated, and very beautiful.
She was away when we stayed there, so we did not meet her personally and therefore I cannot accurately report on this as a shared space. She made special arrangements for us to get in when we arrived, and thoughtfully checked in with us by email.
The apartment is in a lovely neighborhood and just a few minutes walk to the metro from where you can get anywhere in the city.
