First the postives, this apartment is in an excellent location! It is so close to the Piazza Navona and wonderful restaurants in this area. The host was very helpful with arranging an airport transfer and storing our luggage. The beds were comfortable. The negatives are for people with mobility issues like me. I chose to sleep on the sofa bed to avoid the stairs. Unfortunately, the bathroom on the bottom floor is like a small closet with a shower over the toilet separated by a shower curtain. Maybe not be a problem for some, but a difficult situation for someone with mobility issues. Upstairs, the Jack and Jill bathroom needs maintenance and the hair dryer was stored next to the dirty toilet plunger.
The kitchen is small, but ok, only the microwave was dirty.
We used earplugs because there was some street noise from people and funnily also from seagulls.
