Sharon's home is in a accessible location in Rome. You should definitely take it if you want safety and accessibility. You could walk to almost all the famous attractions of Rome.
Overall my stay was nice. House is as it is in the pictures. There were few problems with the fan and there was no air conditioning so it could get a little difficult in the summers. But I am still satisfied because the price is quite reasonable.
Sharon herself is quite an interesting human. She gave me a lot of good suggestions for my stay in Rome. Overall satisfied.
