Overall, Alexandra's apartment was very clean and at a great place to stay. We were walking distance to Old Town, and very close to lots of restaurants and public transportation in Gros.
The only difficulty we ran into was checking in early. Alexandra was very responsive, however, the instructions for locating the lock box was split between a variety of our communications taking some time to piece together how to locate our keys.
Also, there are a number of rules for this unit, so be sure to pay close attention to these during your stay.
