We had a fantastic time in Rome, the apartment had everything we needed. The location was perfect, close to great restaurants for dinner.
Locations wise it was easy to find, we got the bus straight from Stazione Termini to the end of the road (number 64 bus!) which was so easy. Then during the trip it was less than a 30 min walk to the Colosseum, the Vatican and other major sites which meant we got to see a lot of the city but all was walk-able.
The apartment itself is small but perfectly formed, it had more than enough room for the 2 of us with a lot of storage, a kitted out kitchenette, washing machine etc. It was clean and well stocked with essentials (toilet rolls, washing powder etc). The bed was comfy and the shower was nice and big. It's on the 4th floor, so a fair few stairs but not too many, plus a lift which was great with the suitcases! The view from the window/balcony over the roof tops was pretty but not massively over looked which is nice.
The whole place was exactly what we needed for 3 nights in Rome.
