AMAZING place! I knew it was right near the Pantheon but you literally walk out the door and BAM. RIGHT THERE! It was my wife and my parents first time in Roma, so I was the "tour guide". This place impressed them so much that we all could have just stayed in the piazza our entire stay and never gotten bored (of course we didn't though. So much to see in Rome!).
If it is your first time and you have any sort of mobility issues staying near a train station may be better. All the walking was pretty rough on my Dad. We all shared the mytaxi app with each other though and received quite a bit of cab fare free.
As for the hot water that other reviewers complained about, we didn't touch the buttons that say "do not touch" so we had hot water. My Dad said his shower the final morning was lukewarm, but nothing cold! Don't touch the buttons and you'll be fine.
Sorry about the pan. I accidentally left it on the stove top while the stove was cooling and we couldn't find any good scrubbers to clean it with.
