The apartment is close to the SaintPaul metro which makes it easy to get to. The neighborhood, Le Marais, is lovely and cute, full of cafés and bistros. Place des Vosges is nearby and the Seine is equally close.
The apartment is very cute and quite old and historic but still with modern amenities. It's cozy and very French! Be prepared for all the stairs and if you have a lot of luggage is best to fortify first with un verre du vin at the bar just next door.
Vinciane is truly one of the most wonderful and gracious hosts I have had the pleasure to meet!
Thank you for such a delightful trip, Vinciane!
