This is a great place for a solo traveler, doubt you can find a place like this at this value and in such a great location. Just know that its located in an old part of the Rome downtown so the building is old and has some quirks of an old building but there is hot water and a nice bathroom so should not be a big deal at all. It rained some of the days while I was in Rome but I was able to just wait it out at the apartment sometimes while it stopped in the afternoon and then just go out again. Since the location is so good I didn't need to use public transport some of the days since you can just walk to all the great locations in Rome, it's very central to walk to the Colosseum or Vatican is just 20-30 mins away and since Rome is beautiful you will see a lot. Charlotte is super nice she will be there to welcome you and give you the best tips.
