Claudia was an awesome and very understanding host! Like idiots, we managed to lock ourselves out of the apartment one night, and Claudia came to our rescue and was totally cool about it. We also couldn't figure out how to turn on the wall heaters, and Claudia went out of her way to make sure we were comfortable.

As for the apartment, the location is very central and all the sites we cared to visit were within walking distance (you can see the dome from the living room window), and it's easy to find as it's directly across from a hotel that is always well lit at night.

As an American, you might find the kitchen and shower a bit cramped, but we never cooked and my wife and I are not big people, so we didn't mind. Finally, like many old apartments in Europe, there is no elevator, so if you're traveling with people with heavy luggage (aka women), get ready for a work out to the 4th floor!
