I just returned from a four night stay at Hotel Fontanella Borghese. Our twin-bedded room was tiny and it was impossible to take a shower without flooding the bathroom floor. In the twin-bedded rooms armoires are also very small and may not have a place to hang dresses. But the location is great, the hotel is spotless and in excellent repair, the air-conditioning works well, it was very quiet (though not very full, I think) and the staff is friendly and helpful. For the money (198 Euros per night in August) I would try somewhere else next time, but if I couldn't find a better deal, I would stay here again. I definitely would not stay here if I were not a small person! Note that the Hotel is in a portion of the second and third floors of a palazzo.
