our apartment position is clearly indicated in our Airb&b announcement, anyway (Hidden by Airbnb) maps helps a lot if it is consulted carefully!
The apartment is not located in the historic center but close: as many reviewers have confirmed the historic center can be reached with a few subway stops, about 7 minutes to Porta San Giovanni. But Rome has archaeological sites everywhere ... The archaeological park of the ancient via Appia is closed by and can be reached walking or biking. I remenber offering you a bike.... Did you visit it?
Let me give you some suggestions for your next trip to Rome:
book an accomodation at the Pantheon or at Fontana di Trevi area if you have problems walking or using public transportation (I understand that 1.50 euros for the metro ticket can be very expensive!);
remember to book your accomodation in advance and not the afternoon before and more than the others raise your credit card ceiling because, if it is true that our apartment is not down town it is also true that the price is lower than any other legal accommodation in the historical center and it is inclusive of cleaning costs and regularly recognized by the Tourist Authority .
Rome is a beautiful city and every visitor deserves to appreciate it to the best of its possibilities.
As for the kebab, no guest has never complained about paying 5 euros for a kebab, however around our apartment there are also a tavern, Mac Donald's, Burger king, many pizzerias, an open market with fresh food and many supermarkets. Real travelers love to discover the surroundings of the places they 're staying and getting in touch with the habits and customs of local (Website hidden by Airbnb) depends on the idea you have of travelling!
However, it has been a pleasure hosting you!
