I just stayed at Mirna's apt in late may 2015. She was a great hostess and person. She took me for a 2hr walk so show me the neighbourhood and since I was travelling alone she offered to meet up to eat so I would not eating alone .
The neighbourhood had lots of restaurants and drinking establishments . it is located between 2 metro stations (3 and 10 min walks).
The apartment was very clean ,comfortable and had everything I needed for my stay . The 1 bed ( i'm assuming the couch turns into a bed but you should ask to confirm ) in the apt is made for a single person . im 6'2 225 lbs and slept comfortably in it .
The shower had pretty decent water pressure.
If I head back to paris , I would have no problem contacting Mirna on using her apt.
