I will start with the positives:
1) the location is fantastic. Right in the middle of everything and easy walking to all of Prague 1
2) the place was very clean. No issues there at all
Now, with the negatives:
1) very basic amenities as compared to the other Airbnb properties that I have stayed out.
2) up three flights of stairs, so don't book if you have big luggage. We had a child stroller with us and it was a hell of a workout to get up those stairs daily
3) 3 beautiful TVs in the apartment, but none of them worked and when I asked the renter, she said that local tv doesn't work and to use my Netflix account:(
4) No air conditioning. I expected that, but I have to point it out here, as it was very very hot in the apartment even with the windows wide open.
