Alessandro was great with communication from the day we got there. He met us even though we were a little late and showed us around the entire apartment. There's a small elevator that you can use, very old fashioned and super cute. He's on the fifth floor so we made a few trips with our bags but his place was totally accessible. The location of his apartment is absolutely perfect, it's a few minutes walk to the Spanish Steps and Trevi Fountain. The Colosseum is a little far so we took an Uber but I'm sure if you had time you could walk there too. Vatican City was also within walking distance. We felt very safe in the area and the building. Our favorite spot was breakfast out on the patio. Super cute space.
There were four of us and we fit perfectly. There were books filling book cases that were really appealing to look into. The bathrooms were grand and really nicely decorated. The air conditioning worked great as well as the hot water. We didn't use the kitchen.
I would definitely recommend Alessandro's apartment to anyone staying in Rome as well as booking it again myself.
