The apartment was beautiful. Right at the top of an old building (no lift so you have to be fit or prepared to become fit but the stairs were an experience in themselves - all polished wood spiralling up and I didn't mind the hike), the windows with their little balconies give you the perfect place to enjoy a glass of wine while watching Parisian life go by. The roofscape was wonderful and we never tired of sitting out and looking at it.
Our host had left some cheese and wine for us by arrangement but had left an extra bottle of wine as well which was so nice of him. Gorgeous stuff.
The apartment was spotless and had everything we needed for the weekend, including a free standing air con unit which was very welcome as the weather was lovely (at least it seemed so for us coming from Ireland!).
There was a folder with loads of suggestions for places to go and how to get there - but we were so close to everything we wanted to see we just walked everywhere - and for local bars and restaurants. That was really handy and we had a great meal in the cafe at the end of the road.
The host was brilliant about organising the key handover (he was away so used bnbsitter and the guy from there was lovely too) and very clear about how to get to the apartment and how long it would take from the airport..
I can't think of a single thing to say against the place although I wouldn't take my aged parents there as the stairs might finish them off!
