Galina's apartment is in a great neighborhood and was the perfect location for our trip. It's small but a perfect size for a couple who plans to spend most of their time seeing the city. Galina was accommodating and very pleasant in our interactions with her. We greatly enjoyed our stay for a week in her place.
The only advice I would give, and this is totally out of Galina's control, is that if you are a light sleeper, consider bringing a pair of earplugs. Sound was not an issue most nights but the window of the apartment faces into a courtyard that causes sound to bounce around quite a bit. One night of our stay, a neighbour was having a gathering that echoed quite a bit in the courtyard and kept us awake for awhile.
We still had a lovely time and would recommend Galina's apartment to anyone wishing to stay in the Montmartre area.
