Helene is a very nice host and her flat is just in the middle of the Marais, a very colorful and picturesque area of Paris. The place is cosy and warm and very easy to reach with the subway. It is just on one of my favorite street of the area (rue de Bretagne) and a very French market (des enfants rouges), a supermarket (Monoprix rue du temple). It is 10 minutes walking from Place de Voges (former residence of King an Queen-have a tartare @ Ma Bourgogne but no credit card accepted).
The flat has an independent bedroom with a comfortable queen size bed and is in a very old and typical parisienne building just in front of a small park.
