Our stay at Dom's apartment was very short but pleasant. When I arrived he walked me through many details of the apartment (how to use the shower, where I could store things, etc) - it is clear that he wants to make sure his guests feel very comfortable and welcome.
He gave me some great advice about some logistics of getting from Paris to the airport.
He communicates very effectively and his English is very strong.
The room is small but neat and in a good neighborhood in Paris.
The only down side is that the apartment is a 5 floor walk-up, so it is a bit of a challenge if you have a lot of luggage!
