It is hard to imagine how Guest Apartment Services could have been any better.  We just returned from an amazing two weeks in Paris and from initial contact to check out, the staff at this company was exceptional.  Christophe, Madame Muller, and our driver, Jean Luc, are committed to customer service in a way that rivals their competitors.  This is our third Paris vacation in three years.  We are most grateful to have found Guest Apartment Services and I cannot imagine using another company in the future.We really adored our apartment, the Ortensia.  Location was so convenient to several metro stations, including Line 1, which is one of the most helpful lines for tourists in my opinion.  The bus, including the #69, also excellent for sight-seeing and picks up just a couple blocks away as well.  However, walking in this part of the Marais was such a pleasure.  Peeking down the narrow, winding streets that beckon you to follow is a memory maker in Paris.  All conveniences are so close.  Lots to do and see. We found our little place in the neighborhood for croissant and coffee, but there are many to select from, as well as cafes, grocers, banks, pharmacies, shops. The Ortensia is my favorite apartment now in Paris after three vacations.  The furnishings are comfortable and the place is stylish.  The cross breeze from the many windows was just lovely.  Everything we could have possibly wanted.  We love the vibe in the Marais!
