My appartement is in Sceaux (Paris), very nice, calm neighbourhood. Paris center is 25 min with RERB train from Robinson (every 8-18 mins) or bus (many options). Classy and high security building. Apartment is equipped simply but fully, very practical; has a big living room + one bedroom+ bathroom +WC+kitchen+ private garden! There are very nice parcs just nearby, really neat and safe neighbourhood.
Very good price for summer just next to Paris in such a nice place!
