Valeria was an awesome host, she helped us with all questions and even helped us deal with a nasty cab driver upon our arrival (which reminds me : USE HER CAR SERVICE! he was great!). Valeria left us toast and jelly and water which saved the day! The apartment is exactly as advertised and in a residential safe area. I only have 2 concerns: 1) the walk to the metro: its true that it is about 1km or a little less, but the issue its up and down hills, so coming down in the morning was no issue, but coming back up after exploring all day and being tired at night its not the best, one of my family members is a little older and she twisted her ankle on the way up the first night. This of course is not Valeria's fault but just so you are aware that the walk back up can be rough. 2) the heater was out when we arrived and it was very cold in the apartment, we slept with our coats and even our hats on because we were so cold. unfortunately my same family member who twisted her ankle also got a cold after the first night :/ I know Valeria mentioned that this was a temporary issue with the apartment complex so hopefully it is resolved quickly. Other than that the apartment and host were great and I'd stay there again if I'm ever back in Rome.
