Our stay with Thea was perfect. Room is as described. Shared washroom with other air bnb rooms but this was never an issue. Found her place quite easily from the airport thanks to her directions and map that she e-mailed us prior to arrival. Thea was also helpful when we asked for directions around the city. The place was clean and the breakfast was great (Italian style - coffee/juice/cookies/pastries). Location is great too! Very close to the Vatican, many restaurants and bakeries in the area and a metro station a couple is blocks from her building.
Would definitely stay with Thea again if I return to Rome.
