I listened to "Romantic Prague" on Audio Europe. Mr. Hewitt mentioned a hotel across from the Astronomical Clock. I thought he said yPrinz, but I can't find that place in my guidebook. Please clarify.
This is that Prague hotel, where you can invest in a drink on their view terrace (it's listed in Rick's eating, not sleeping section, on p. 151 of the Prague & Czech Rep book): https://www.hoteluprince.com/.
