I was there for 5 weeks. The room is good. There is a futon on a bed-sofa, not too hard and not too soft. I have a good sleep so I had no problems with the noise from outside the buliding and the windows isolate very good - Paris is not a very quiet place ;)
Ben let me use the kitchen so I coocked pretty much every day, sometimes with him.
There are two metrostations close to the appartement, line 8 and 6. A nice parc is very close, like 2 min walking and a few places to buy whatever you need untill 9pm.
Ben showed me a lot of things & told me what I could do and where to go, he knows a lot of things and I already have a lot of ideas for my next trip to Paris.
I had a good time at his place. Ben is a very helpful uncomplicated and friendly host. Merci pour tout Ben!
