We had the most amazing stay at Alessandra's apartment! We didn't arrive until midnight but Alessandra was happy to wait up and also stay to give us great restaurant and bar recommendations.
The flat itself was lovely, really warm and cosy, and we enjoyed having breakfast with the shutters open and drinking a delicious espresso from the coffee machine.
Testaccio is a great neighbourhood if you want to try local restaurants Romans eat in rather than tourist traps...all three places we tried within a couple minutes walk of the flat were fantastic (Trapizzino as recommended by Alessandra, Lo Scopettaro and Antico Forno). We wanted to try the recommended pizza place Da Remo, but the queue was huge on Saturday night - bear in mind if you want to visit.
It's possible to walk into the centre of Rome from the flat but it's easier to catch the Metro from Piramide, which is about a 15 minute walk from VespucciFortyOne.
We loved staying at Alessandra's apartment and would definitely visit again. She was a very helpful host and even called a cab for us to the airport when we left. It's the perfect place if you want to spend the day sightseeing but enjoy evenings relaxing in a comfortable flat, or out and about with locals rather than tourists.
