Positives: The apartment is in a great location. Really, the area of Monti is full of locals. Of course there is tourists because of the proximity to the Colosseum however there is a lovely little square around the corner where we had Aperetivo and truly felt like we were immersed in the local scene. It feels very safe. The unit is nicely decorated with most things you would need, towels, blow dryer, iron and ironing board, washing machine (which i was tempted to use but didn't because I got intimidated on how to work the dials). The apartment has a great little air conditioner which is surprisingly powerful. And really useful as it was still pretty hot in September. There is also a Netflix subscription built into the TV for you to use. Usually we don't watch tv on vacation. But it was actually nice to watch a familiar show in english before bed after traveling so long through Europe. The apartment seems to be newly renovated which is a plus. The bathroom has a nice modern shower etc. There is the terrace up the stairs in the apartment but we didn't really get to enjoy it. It was still mosquito season and it really needed a good sweeping from all the leaves. I'm sure it would be lovely to sit out there in the cooler months.
Negatives: The space is pretty small. It really is just one room with the little kitchen and bathroom. As you see in the pictures the couch folds down and the murphy bed pulls down from the wall. The bed was actually pretty comfortable. But there is not a whole ton of walking around space. We just really used this as a place to sleep since we were sightseeing so it wasn't a huge issue for us. I personally don't think it could accommodate more than two people comfortably. The unit is very dark. There is not very much natural light. It is kind of an interior unit in the building. so the only natural light you are getting is though the skylight from the terrace. Which isn't that much. Obviously this cant be changed. But if a lot of natural light is important to you this may not be the spot for you.
Overall, Salvatore's place is pretty good. The location while not near some of the other major sights is in a very lovely area that you may not have explored on your trip to Rome if you didn't stay here. It is pretty clean and has all the modern amenities you may need. It has charm even though its not the biggest space. The biggest perk was that Salvatore was extremely responsive. He is a good host. When we were talking longer to arrive from the airport than anticipated he arranged for his colleague to meet us with the keys. Who was nice and informative. We had no issues arise during the stay. And it was an easy and seamless check in/check out process.
