I highly recommend Simone's apartment. The location is perfect. It's in the heart of Rome, very near to the Pantheon. The apartment was cosy, it had a comfortable bed, air conditioning, a well equipped kitchen and a clean bathroom. There was even a separate room with espresso machine and a bar ideal for drinking coffee (although don't miss the chance to go to Tazza d'Oro, a coffee shop which is very close and serves amazing espresso and fresh croissants). If you are tall, make sure you can fit the bathroom, as it is quite low (about 1.90m high). Simone is always very friendly and he will give you valuable hints, especially when it comes to the transport.
