This is a lovely place to stay. I can't imagine a place more convenient for someone wanting to see this beautiful city. We feel fortunate to have been able to book it again. We love to walk and see the sights and this place suits us to a "T."
The noise from the surrounding city and tourist zone is very minimal in this clean, comfortable home. If you are visiting in summer, you will likely want to leave the windows open to enjoy the cool breeze from the courtyard (as we did). As a result, the other guests across the courtyard can occasionally be a bit loud as they come back home from a night out. Other than that, you'll be surprised how quiet it is, even though you are literally steps away from Old Town square.
Also be aware that the bathroom window (which is high in the wall) does look out onto a garden. Occasionally someone will wander through, but they don't have a direct view into your bathroom, so I wouldn't really consider that an issue. For my part, it was nice looking up at the vine covered walls and listening to the birds sing. Very restful. We sincerely hope to stay here again.
