Lilly's place was perfect and exactly as described. The location is really great - a very quick tram ride into Trastevere and the city center. The tram is extremely reliable and comes every 5 minutes or so, running through the day until after midnight most nights. The neighborhood Lilly's apartment is located in is very residential and has some great bakeries, cafe's, and restaurants. La Gatta Mangiona (literally right down the street, on the same block) is AMAZING and probably the best Napoletana stype pizza in the city.
We didn't spend a ton of time in the apartment, but it was perfectly suited to our needs and was the perfect base for us.
I would recommend this apartment in a heartbeat! Lilly was also incredibly kind and helpful, giving plenty of recommendations and suggestions and checking in throughout our stay to make sure everything went well.
Thank you so much, Lilly! We had a great time and will be back the next time we're in the city!
