We had a lovely stay at Piere and Aline's place. They are very nice and friendly people. The house lies in a quit neighboorhood and the room was great and comfortable. In 8 minutes you walk to the metrostation, in our opinion it is very close and you will be quick in Le Marais or the Republique station where you will find 4 different metro lines. Paris was great and so was our stay at Piere and Aline's, we'll definetely come back! :)
