Overall a great stay if you're a tourist just visiting the city!
I stayed for 1 week. Location is great, the apartment is really really really nice, communication was always super easy, check in experience was great.
Honestly, everything is great, a part from 1 thing: there is basically no natural light coming in the apartment.
So, if you're planning to spend time in the apartment during the day to work for example, like I did, I would not recommend it.
If you're just visiting the city and want an apartment that has absolutely everything, is in a great location, is spatious and just makes you feel at home, then I would recommend it.
