Very handy place to stay in the Marais, close to shops and restaurants. The main entrance area is quite old and stairs are very worn so keep this in mind if carrying heavy bags up the stairs. The apartment is large and bright with good space. Only one shared bathroom which has a bath with the overhead shower in the bath. So maybe not advisable for a large group.
But that said it is a great apartment, in a central area, very quiet street, good value and Florence is a lovely host!
