Tania was great! Brilliant host. She's an experienced traveller who makes it easy for anyone arriving in Rome to get settled quickly. She's arranged discounts for her guests at some of her favourite local restaurants - that should give you an indication of the thoughtful, organised person she is.
The location is perfect if you want to be central to the old part of town. It can be noisy in the streets, but once inside the flat you leave the noise behind. Lots of restaurants nearby.
