Our stay at Vladimir's place in Paris was absolutely lovely! Great location, Vladimir communicated with us clearly about how to get into the flat, and the flat itself was very cute and cozy, with a nice view over Paris. The location so near some of the main attractions of Montmartre was just fantastic for us and a great lifting-off point for anyone visiting Paris. It's on the 6th floor with no elevator, so not ideal for people with limited mobility, and very small, so best suited to people who really love each other ;), but it was perfect for us.
There was an odd scent coming from the bathroom often but it was mild enough that if we closed the door it didn't bother us. Highly recommend!
