We really loved Khristina's apartment! It was very clean and comfortable, and everything we needed was there. The decore and appliances were new and nice. We also loved the little details reproduced from the Parliament Building - we won't spoil it for you, so you can see if you can spot them yourself.
The check-in is super easy, and we felt very safe in the building. There was some pounding club music nearby for just an hour or so in the evenings, but it stopped around 9, so not a problem and it was otherwise quiet at night. The sofa bed is also very nice - not a design we've seen before, and much more comfortable than your usual pull-out.
We highly recommend Khristina's place!
