It was great to stay slighty out of the centre in Marie's place but at the same time be within 15 minutes' bus ride from most attractions. The 5C bus took us almost everywhere we needed to go and you should definitely take it from the airport - if you take the metro you have to walk for about 13 minutes from the stop with suitcases. The apartment was really clean and had everything we needed. Two of us slept upstairs, one on the sofa bed and one on the floor mattress and both were very comfortable. Despite being fairly built up, the neighbourhood was really quiet and felt very safe. We heard hardly any noise from the other occupants in Marie's staircase. Marie always responded quickly and I would really recommend this place.
