It's mixed bag. Good location, but in a road with busy traffic (although windows are very good). The door is not that well insulated and one hears people in the corridor.
I stayed 10 nights and they did not change sheets/towels. They did not clean the bin in the main kitchen either, and during the last two days there was bad odour in the full flat.
It is beautifully decorated, but impractical (it is not well thought through): the curtains are not black-out, the desk? and stool are not comfortable to sit down for more that 10 minutes. More crucially, there is not a place to hang the clothes (or the towels in the bathroom).
