Nathalie's place is exactly as described. We came from CDG airport, took RER B train directly to Citĕ Universitaire station. A short walk and we were there. The apartment is very clean and has a good mix of modern amenities with historic windows, floor finishes. It was great to have breakfast before stepping out for a long day, fresh bread fruits cofffee jam butter etc..
There are multiple voleb(bike) stations on rue de bobillot , so use it. Bus stop is right in front of the building as well.
Overall it was a great experience and I highly recommend Nathalie's place.
