The flat is a perfect base for Paris. It is very conveniently located not far from RER B and only a few stops from the very centre of Paris. The area felt safe and was very quiet at night (no traffic sounds audible other than the odd siren in the far distance), the residents were very friendly and helpful. The flat itself is small, but clean with all necessary amenities.
I would happily recommend this flat to people looking for a base for exploring the city.
We found catching up with the host to take the key mildly problematic...I feel a better plan should have been in place prior to us leaving (our flight was delayed by 2 hours - which the host was aware of prior to our departure from the UK, but even so the only instruction was to call once we had landed). Once we had landed however, we were without mobile service and couldn't find any wifi spots...it all worked out well though and he was friendly and helpful.
I recommend this flat!
