We (2) stayed in Lemon House (as Orange House was occupied) for 4 nights, we found the property easily with instructions provided & a map from the hop on/hop off bus people at Piazza San Pancrazo, after arriving by shuttle bus from the train station - easy. Access to the house is via steep stairs, keys were easily accessed as per instructions.
the house is as described and located very close to all attractions, shops & restaurants.
We did have an issue with noise from the street - in particular the bar/cafe across the street late at night & garbage collectors early in morning, however some good earplugs alleviated this. The price you pay for the central location. There was plenty of cooking implements & crockery etc. to self cater. The bed was quite firm. Having a seperate lounge & bedroom area was great. TV was only Italian stations (no problem !)
Andrea was very prompt in replying to all emailled/text communications and was very helpful in answering all of our questions.
