My girlfriend and I visited Rome for a long weekend in April. We were looking for a comfortable property centrally located, without paying the Earth.
If location is high on your priority then Cendra's place is definitely worth considering. It's a stone throw away (literally) from the Trevi fountain, and within walking distance of all the major attractions in Rome (we walked everywhere apart from to the airport home!).
The apartment is located on the top floor of a block on the pedestrian road by the Trevi. It is small, but comfortable. It is equipped with a queen size bed, a kitchenette, small dinning table, a bathroom with shower, and it also has air conditioning. It has plush decor with a touch of Roman influence.
The host Cendra is lovely, and very helpful and quick to reply to any questions you may have. She arranged for us to be picked up by a chauffeur from the airport (Ciampino) for 30 euros, which we generously tipped. On the way home this cost 45 euros to my surprise.
Cendra put together a information brochure for tips on getting around Rome and the best restaurants to dine in which was very helpful.
We really enjoyed our stay and would recommend to singles/couples who are looking for accommodation in a great location, and for a good price!
