Really enjoyed Cedric's apartment. It is 1 block from a larger supermarche that is well stocked, and only 1 small block off rue Beaumarchais. The closest metro is saint sebastien on line 8. Very convenient to be so close to a metro stop (less than 2 min walk!) after a long day of walking and site seeing. Stock up before your day at the supermarche with drinks and snacks.
The apt private patio is relatively large, fun hanging out there. A variety of plants line the long courtyard and somewhat screen everyone's patio. Set up a VPN (HMA! has a free 7 day trial) to hack thru your American cable TV provider's international firewall and enjoy a live game from your streaming app cable service with a Rhone blend. No American sports stations on the TV, and the games start later at night in paris, good timing after a long day out. Note, your iPad speakers may be a little loud for the locals, keep it down or you may get an excusez moi thru the patio foilage.
This apartment is closer than you may think to a lot of the action in Paris. Rue de Rivoli is walking distance, and the popular falafel place in the marais is only a 12 minute walk. Rue Turenne is so close. Also, a lot of street art is on this side of the city, put a loop together fron rue Beaurepaire thru reu Bichat, reu St Maur, and rue Denoyez.
For small bar hipsters, the Zero Zero bar is literally across the street. Have a couple Belgium IPAs (actual pints) on draft for only 4 euros during happy hour and hang out on the sidewalk with the DJ doing his/her thing.
Ofo has a lot of bikes around. Use the Orange wifi service and hop on an ofo bike for faster exploring.
Great location, convenient logistics, hard to beat. Run, don't walk, if this apartment is available for your dates!
