I do appreciate living in the historical building and appreciate the host do everything she can to make everything as smooth as possible. As all the other comments we had read below, the room was sparkling clean, pretty specious, communication is excellent and we loved the washer and dryer, etc.
On the other hand, there are something else I would like to share my experiences during my stay.
1. 87 steps to get to the apartment ( with landing in between)- It is actually the 4th floor if count in US way. There are total of 87 steps. Host did mention there is no elevator in this building and seems like it is in the process of reviewing permit. If you cannot lift your luggage, it is challenge for you to get up to 4th floor.
2. Shower: there is no place to hang in your shower head. If you wash your hairs, you are not hands free. The shower room is very open, you will feel cold during your shower.
3. Smoke building- The moment you walk into the “building”, you can smell it. The apartment we stayed is actually a non-smoking room. But maybe because it is a historical building so the smoky air flow thru ventilation. If neighbor is smoking, you can sense the cigarette flow into your room.
4. The neighbor upstairs is actually walking pretty heavy foot everyday in the morning and in the evening.

My sister and I had a great time in CZ. The location of this apartment is excellent and feel safe. The apartment is literately right next to the national theater. I will still give a high rating, but due to the difficulty of the luggage situation I am not certain if I could do that all over again.
