The right size for 1 person or a couple. 2nd bathroom does not have it's own door, rather the living room door serves as the separation for privacy. Convenient location for traveling, close to bus and tram. easy to walk to/from the city center. My only issue was that there was no heating on my first night due to a faulty thermostat, and was fixed the next afternoon. The temperature took days for it to adjust.
Sadly, the host blamed me for lack of heat because he thought I was adjusting the thermostat when I did not. Another host came by the apartment the next day to change the batteries and reconnect the WiFi to it to 'fix it'. It took about 2 full days before the temperature went up 1 degrees C. While I only needed the apartment to be around 18-19 Degrees C, it stayed between 16-17 degrees C for the first 3 days we were there, and slowly kept climbing each day.
Walls are a little thin, so you will be able to hear the neighbor flush/turn on their shower through the bedroom wall. If people are hanging outside being loud, you are sure to hear them.
Though I believe this place was comfortable and convenient, I will probably look for other accommodations next time I stay in Rome.
