Location :
Claude's house is in very safe residential area near Pont Mirabeau.
There are lots of local restaurants and shops (inc. Monoprix and Laduree!) near home, (5-10 min walking distance) and is aprx. 20 min walking distance from Eiffel tower.
It could be little off from the main attractions, but so it provides very comfy and local vibe while it is still in very reasonable distance that you can enjoy the city.
Also, it will offer you different view of Eiffel tower while before and after you explored the city.
(I loved the walk on Cygnes, the narrow and long island from Pont Grenelle to the famous Bir Hakeim.)
Enjoying white Eiffel and walking back to your accommodation without feeling scary must be extra point to their place. :)
Room and facilities :
Room is big enough for an asian girl's standard. :)
It has nearly everything you'd need during your trip.
Small fridge, a microwave, a kettle and of course a bed and a desk.
I cannot say the bed is very best but still enough to lay and fall a sleep with my tired legs and everyday, I slept like a (tired) baby. :)
And it had lovely huge window with the view of Paris-! (You can enjoy the real Paris-like view (which means with river Seine,) from the window in living room though. :) )
Separate shower and toilet is just out of the room and are to be shared with other person, but I never had problem while my 4 nights stay. (I didn't even face him!)
The whole apartment is super local with lots of lovely neighbors.
I didn't know that Parisiens greet even to strangers and regretted my short french. :) (So why not to prepare some more words to greet your neighbors? ;))
And it needs a key just to enter the apartment, which feels much much safer, even the whole area is in very safe mood.
Communication :
Since everything I needed were in room and already provided, I didn't much need to bother them, but I'm more than sure they'd have helped me more than my expectation. And other communication, like some of my questions, and for check-in/out was great and within very reasonable time.
Overall highly recommended and I'm hoping to come back here soon for my next trip to Paris. :)
