Viktors place is great value for money and in a great location to explore Prague. The only thing to be aware of is the the building is old with high ceilings and therefore echoey. You can hear people coming in and out of the building and that can be noisy at times. But otherwise, you get a lot more for your money at Viktors place then you would at a hotel.
I do recommend if you are looking for an affordable way to explore Prague!
