If you are looking for a no-frills apartment simply to lay your head for a couple days, this place will suffice. However, if looking for anything more or staying in excess of a couple days, I would suggest you look elsewhere.
Positives: the apartment is in a great, central location, easily accessible to most Prague attractions, and I felt safe throughout this area (though there are a lot of very intoxicated people barhopping on the surrounding streets throughout the weekend).
That said, the place was old and in dire need of a deep cleaning and some basic repair work. The bathroom was dirty, the bed uncomfortable, the internet slow, and the curtains in the bedroom did not cover the entirety of the window, leaving the room exposed to the building full of windows located directly across the street. Perhaps the most disappointing was a lack of basic items that I have grown accustomed to at every AirBnB that I have ever stayed in, notably: shampoo and paper towels. The first thing I had to do after arriving was to make a trip to the grocery store so that I could shower properly.
All-in-all, it is very clear that the owner cycles people through this place at a very high rate, and the apartment condition reflects that. In the future, I’d spring a few extra bucks and stay at a slightly nicer place.
