I had a very nice stay at Hotel City Bell.
The hotel itself has a very nice location, away from the busiest streets, but close enough so thet you can get to anywhere in the city by foot or public transport. There are markets, restaurants and bars within a minute or two of walking.
Breakfast was good. Covid-safe, so selection is understandably somewhat limited.
The rooms are very spacious. I was actually surprised by how roomy they were (I stayed in two because I extended) given the relatively low price. They are not the most modern-looking ones, but they have a nice bed, decently sized tv, shower, łots of natural light from many windows.. overall good!
What I liked most were the staff. They were very friendly and welcoming.
There did not appear to be any English speaking TV (news) channels. Wifi jumped in and out a few times, but was mostly ok (they have extenders seemingly all over the place, but not sure if operational). I am guessing you are not going to Prague for wifi or tv, but just fyi if this is very important to you.
