Great location along a busy and mostly-pedestrian street less than a 5 minute walk from the Pantheon. The space was lovely, big windows, well equipped. Jacopo was a great host - helpful, prompt and friendly. He allowed us to drop off our luggage early, which was such a gift. Second bed is a standard sofa-bed - with standard sofa-bed comfort. Beautiful old building - we loved it.
A few things to note as you're deciding whether to book this spot:
1. The apartment is not the quietest - especially if you want to have the windows open. The sound from the narrow road below funnels up to the 5th floor very clearly - tourists and revelers at night and construction/deliveries in the morning. It's just fine with the windows closed.
2. Elevator is a bit tricky - no floor numbers and manual stop. Made for some rather hilarious situations where we kept having to go up and down to get the timing right on when to open the inside doors to we were well enough aligned that the outside door would open. By the end of our first day, we were pros.
Overall this was the perfect spot to start our trip.
