I would definitely stay here again. There's nothing quite like looking out the window onto the spectacular view of the Pantheon and the Piazza della Rotonda. This is truly a great location for being in the heart of it all and being able to walk everywhere of interest. We loved every minute of our stay here.
The apartment itself is clean and comfortable and suitable for a couple of people but it would be a bit tight for 4 people. The bathroom and shower are on the small side but perfectly adequate. The pull out couch could be updated. But the spectacular view and location makes up for everything. Having wine shops, supermarkets, and restaurants literally outside the door is a real bonus.
Communication and check in with Emiliano and Maria was prompt and courteous. In short, I would definitely stay here again when next in Rome. Highly recommended.
