The sound insulation is an absolute nightmare. From the apartment, you can hear every noise and activities that are happening in the building (travelers, residents, cleaning service). Special thanks for the kids that go to school every day at 7 a.m., running and screaming. Of course, it is not the fault of the kids, the fault is on the poor apartment soundproofing and money savings that the owner have tried to make during renovations. The street is also noisy in the late evening and early morning. It is a shame because the apartment is well equipped, but furniture is average (squeaky bed). In addition, the apartment is much smaller than pictures seems to show. Finally, location is fine, near public transport.
To conclude, this is not a luxury apartment, and it is not worth the cost (in term of money and of sleep quality).
