We stayed at Simone's place for 4 days and there were 5 of us. Check-in was seamless and Simone was very attentive to make sure everything was smooth for us. The apartment itself was a little compact but it worked even though there were 5 of us. The location is super central to everything. Termini is a 15-minute walk and there are all kinds of amenities within a 5-minute walk such as supermarket, metro and tons of restaurants. With the exception of the Vatican, we pretty much walked everywhere. The Colosseum is a 10-minute walk so we got some great day and night shots. Everything else is a 25-30 minute walk. Simone also added a lot of nice touches like snacks, ingredients for morning coffee, etc. I would highly recommend this place.
