Thea's apartment is very close to the Vatican (10min walking to the museum entrance, 15min to St.Peter's square) and has a bus stop just in front of the door, so you can easily go to other parts of Rome. Thea can give you a lot of recommendations about public transport, restaurants and things to do in Rome. You get sweet cookies and coffee or tea for breakfast, and there is a fridge for the guests that you can use for food; but there is no oil/vinegar/knives and fork for cooking. What disturbed us a little was that for 4 rooms à 2 persons, there is only one bathroom, so there was a bit of a battle for the shower every morning. Apart from that, I would recommend staying here, especially if you are planning to go to the Vatican.
