Nico was an excellent host! Our train arrived into Paris a couple of hours earlier than check-in at 2pm and Nico met us early and let us leave our bags at the flat so we didn't have to drag them around with us until check-in. We also had an evening train on departure and he was very happy for us to leave our bags for the day after we checked out. He met us later on so we could collect them.
The flat is exactly like the pictures. Really cozy, comfortable and clean. Excellent location as well. Very central and very easy to walk everywhere. And for those attractions a bit farther out the metro station is only a five minute walk from the flat.
Nico also had lots of maps and took the time to show us things we should do and places to eat at. He was very happy for us to contact him at any time with any questions. This was a fantastic place to stay and I would recommend to anyone coming to Paris.
