Tanja's place is really central - about 5-7 min walk from the Termini station. It's a very tiny apartment with all basic amenities including a coffee machine and iron etc and it has a very nice terrace. I stayed here with a friend and We had just 2 challenges - 1: we only had 1 set of keys so we had to coordinate with each other to get home at the same time. (If you need another set please do let your host know well in advance). 2- the apartment doesn't have a proper bed. It's a sofa cum bed that's a bit uneven and a single folding cot that's just under the sloping ceiling and we bumped our heads a couple of times. However considering it's a compact flat in a very central location we were fine to overlook these.
Tanja is a very helpful and kind host. She was in time for check in and explained everything very well. She's very responsive with any communication and also makes suggestions for places to eat and see. Overall a nice stay.
