I am in love with Thierry's apartment! I want to buy it! The whole apartment is very confortable, perfect size for 2-3 people, the balcony's view is beautiful, the bathroom is very good, very strong shower's pressure, very hot water, kitchen has everything you need (coffe, tea, chocolate, salt, sugar, spcies etc), super confortable bed and sofa. There is also a elevator (not commum in Paris.).
Location is perfect, you can walk to everywhere (Louvre, Jardin de Luxemburg, Hotel de Ville, Notre Dame etc), and is also very easy and fast to get to/from airport as there is a direct RER line to St. Michel.
Thierry is very nice, always worried about our stay, always available to answer my questions and one week before I arrived he sent a very detailed email with everything I should know about the apartment.
It was very easy to get the keys even thought I arrived very late.
Thierry even let us a bottle of wine!
When I come back to Paris I have no doubt of where to stay! Do not think twice! Book it!
