Definitely not a good fit for a long term stay. It's not a proper hotel but also not an apartment.
The GOOD: Location. Very centered yet on a quiet street. Rooms are very spacious, well designed. Received a free room upgrade. Staff was very present and friendly.
The BAD: The list is long... The room had a very foul smell coming from the bathroom. If your room is near the elevator, be prepared to hear everyone coming in and out. Rooms are not cleaned during the stay, so after 6 nights, a lot of garbage accumulated. As such, coffee / wine glasses become very unsanitary as well by this point. Room only accessible via mobile phone so if you're running on low battery and out you have to return to the hotel which is very unpractical. The hotel charged me a fee prior to my arrival which was not listed in my reservation quote and only received a refund after my travel agency intervened.
BOTTOM LINE: Good concept, bad execution. For a similar price you can find a better accommodation. Either a proper hotel room with cleaning and amenities replenishment or a proper apartment with the relevant utilities to do it yourself.
