Me and a friend lived in Sophie's apartment for a month, and were very happy! The apartment is located near two subway stations and everything you need is nearby. The apartment is very well suited for one or two, and the balcony was lovely. Sophie's been great at communicating, answering our questions and making sure that everything was good!
Worth mentioning is that the doors to the balcony were not very well sound-isolated, and since there's a church on the street that rings the bells at several times a day one should be prepared that there'll be some noise.
All through and through we are happy with our stay and would recommend it :)
