Just return from paris and i want to share some advises with you :
first of all, if you go to the louvre museum, don’t take the main entrance but the “lion’s door” this is a small entrance that is hide and nobody knows it.
second advise don’t take the taxi from and to the airport but ask to your hotel reception a shuttle service around 18 euro per person.
third advises : choose the perfect side of paris Left bank or right bank) I prefer the left bank which is more american.
last advise : I founf my hotel on http://www.paris-hotels-charm.com there are 4 charming hotels and my was the hotel manoir saint germain. I loveed it, it was charming just refurbished and what I prefered is that the decoration was very parisian and not too modern. I like the ida that you can only find this kind of hotel in paris.
nice trip !
