1. The apartment was as advertised. The furniture and the character was great and we didn't feel like we were in a generic hotel/apartment at all. We were particularly taken by the big set of keys that we needed to get into the building, then to unlock the front door. But it did make us feel pretty safe!
2. There is a small lift but good enough for me and the luggage so my wife had to walk up the stairs :-) But note that there is still a half flight of stairs to get to the lift landing.
3. The apartment had everything you need to stay. Just note that there's only enough hot water for a couple of showers then you have to wait for it to reheat. The kitchen is tiny - not enough space for two people! There is a microwave and a kettle, and two burners. Useful for the moka pot. Coffee powder was provided and it made good coffee. The sitting room is a great place to hang out and the huge dining table has lots of place for stuff we bought (biscuits, fruits, etc) for breakfast. By the way, there are a bunch of smaller supermarkets within a few minutes walk, and Elena had provided locations and directions in a little folder in the apartment.
4. My daughter joined us for a short while while we were staying there and Elena made up a sofa bed in the living room (for an additional charge/night). We found Elena very responsive and accommodating to our requests. On the last day she helped us book a private car to get us to the airport.
5. Just a note that the apartment isn't particularly quiet - the sounds of the neighbours and the street are very evident. This probably is quite authentic but does make it a bit more difficult to sleep late on holiday or to go to bed early.
6. The location was both good and bad. We had previously stayed in Rome in a different part and really enjoyed that. This time we thought to stay closer to the central sights. However we found the restaurants and pizzerias here to be of much poorer quality and more expensive than the areas 15mins away. Also as there is quite a bit more nightlife in the central area, it can be much more noisy until the bars close.
7. In summary we liked the apartment but did not like the location or the amenities around it.
