We really enjoyed our 5 day stay at Chiara's appartment! It is only a few minutes on foot from the Gare de l'Est station and near two metro stations. It is a great place to explore Paris on foot (we usually started walking from the appartment in the morning and when tired in the evening returned to "Republique" metro station by train). Lots of nice shops, cafes, etc. around.
We did not meet Chiara personally but she supplied all nessary information and a long list of things to do, see, eat and drink via email and was also available via text message when we had some little questions.
The appartment is very cosy, well equipped and nicely located and we really enjoyed our stay there.
So: Two thumbs up!! If we come to Paris again we will make sure to stay here again! :-)
