Luisa and Antonella's apartment is very clean and spacious, with plenty of storage space (both upstairs in the bedroom and downstairs in the lounge and dining room areas). It is located very close to the Colosseum and the surrounding museums and places of interest. It was about a 10 minute walk to Trevi Fountain, 15 minutes to the Spanish Steps.
The apartment itself has 2 x air-con units (one downstairs and one upstairs), whilst they are a little noisy, they worked well and we were comfortably cool inside the apartment. We didn't make use of the kitchen facilities, although there was everything there to cook for yourself if you wanted. There is also several small/cosy bars and restaurants on the same street, along with a couple of small corner shops to buy food/provisions from.
Our only minor issues were with the Wi-Fi signal which was very weak upstairs. It could really only be used when downstairs in the lounge area. Also, as someone who normally likes to sleep in the dark, the lack of proper curtains at the front of the apartment meant that sleeping at night was a challenge (the street outside has lots of electric lights during the night and the sun blazes in from sunrise). If you don't mind that then this won't bother you at all.
We found that travelling around Rome by taxi is very simple and cheap - even simpler if you download the 'FREE Now' taxi app. We found it simpler to book a taxi to/from the Hotel Forum, a 1-minute walk from the apartment. You can pay using Apple Pay or with any credit/debit card. Worth noting that Uber is much more expensive in Rome than taxi's.
