We had a perfect stay in Sylvain's appartement during NYE. His flat is very spacious, clean and modern. We felt very comfortable. To have two bathrooms was perfect for us two couples.
There are a lot of public transport options with two underground stations and a lot of busstops. Best is to use google maps and look for the best connection.
Overall Sylvain as a contact and his flat were superb. Nothing to add. :) Would highly recommend Sylvain's flat to everybody.
