My girlfriend and I stayed at Ana's from Christmas Eve to NY day. From the moment we booked to the point of check-in Ana's communication was amazing. She was also very friendly when we met.
Location is amazing, a block away from Gare de l'Est, one of the major Paris metro stations. For anyone saying the neighborhood is sketchy, don't be afraid. We came back multiples nights past 2am and were never harassed or felt endangered.
The apartment itself is 2 levels with a spiral staircase. Everything was very clean - from the bathroom to the bedroom. Ana has everything you need to cook meals. Just make sure you bring towels - it's noted in the description. There is a washer in-unit, but no drier. We hung our clothes over the heating vents and staircase, and they were dry by the next day.
We were very happy with our stay and would highly recommend this everyone. Thanks!
