I spent a couple of nights here while staying in Prague for a conference, based on a recommendation from the organizers.
The hotel faces directly onto Wenceslas Square and it's easy to walk from here to basically anywhere in the Old Town. There's also a major metro station nearby, putting the rest of the city within easy reach. It should be noted that, because the hotel is located in a pedestrian-only area, taxis and shuttles won't come directly to the front door, so expect a short walk (about a block or so) if going somewhere by car.
The room was well-maintained and clean, with a modern style. Neither the chair nor the bed were overwhelmingly comfortable but were adequate for a short stay.
I only ended up interacting with one member of the front desk staff; however, she was incredibly friendly and helpful as I found my way around the city.
Finally, take note! Many review sites seem to conflate the hotel with the restaurant located on the ground floor. When I looked, a lot of people seem to have had poor experiences at the restaurant, but this shouldn't reflect poorly on the hotel - especially when there are dozens of alternatives within easy walking distance.
