Maria is friendly and explained everything very well and we didn't have any problems with finding the key.
We loved birds feeders outside of the window.
The apartment gave a feeling of life in the 18th century. It is full of antique furniture. It is nice, but I had a fear that if we would spill water or break something, we would have to pay a lot. So, I wouldn't recommend staying with little kids there or having parties. It is like staying in a museum :-)
Location is excellent -- in the center, close to the longest shopping walking street in Europe. And very close to a Metro station.
But the problem is that it is close to a cheap bar as well and every night we had to listen to drunk people shouting outside. The windows don't have any anti-noise protection. We could hear every step of people walking on the street. ​
And the most disappointing thing was that there is only one regular bed + one sofa. This place is perfect for young couple + maybe 1 person who doesn't mind to sleep on the couch. It is advertised that there are three beds, but the host means 2 air-inflate mattresses. We had to sleep on one; it is uncomfortable and cold — I had to cover it with an extra blanket under the bed sheets. Even if you are okay to sleep on air-matress, you need to blow out it every morning, because It occupies a lot of space. You can't feel comfortable there with this big thing on the floor; you can't use a kitchen sink for example. And honestly, I was unhappy that I had to take care of inflating the mattress when I came in the night time with a kid (8 y.o.) and my old mom (75 y.o.). This "second bed" wasn't prepared, and it took a while to figure out what we can use to sleep on and fill-up the mattress with air. Fortunately, the host was online and explained that.
