Great apartment with everything you need (washer & dryer, too!). Excellent location - away from the touristy spots yet very close to the metro and in a quiet neighborhood. (And it's within a walking distance from the Vatican!)
The place is clean and efficient. Marco is a wonderful host - we got lost trying to navigate those little confusing streets and he rescued us. He is very prompt with his responses. He doesn't speak much English but if you know a little Italian, he is very easy to understand. He is warm and friendly.
We had a wonderful visit and the next time we're in Roma, we'll definitely stay there again.
