Amer's Bed & Breakfast is a great place to stay for short to mid term stays in Rome. Being so close to the Vatican city is definitely a highlight and you could enter Saint Peters square in about 15 - 20 minutes of walking. There are a couple of bus lines close by that will get you into Rome central and a metro station 10 minutes from the B&B that can do the same.
The room we stayed in felt spacious for just the two of us while still having plenty of furniture for storage and a TV. The air conditioning in this room was so good that we had to keep turning it off after a short while because the room became so cool in the hot summer. Coupled with the very comfortable bed, we had a few excellent nights of sleep which definitely will help you if you're going to be exploring a city as big as Rome.
The bathrooms were both sparkling clean and one of them even has a bathtub which I felt is usually quite rare in shared accommodation. The kitchen was well equipped, allowing us to prepare full meals if we wished - providing we didn't take too long and washed up afterwards (both fair). There are some croissants and small pastries available for breakfast. There is a supermarket across the street if you need groceries or ingredients.
Amer and his father were very kind, welcoming and gracious hosts. Amer welcomed us, gave us great advice for visiting the city and assured us to speak to him if we needed anything. We were very grateful to have him as our host.
If you are looking for a reasonably priced stay in Italy's most popular city but one that doesn't skimp on any of the amenities or hospitality - look no further than Amer's Bed & Breakfast.
