We stayed at Alberta's apartment in the end of November for 4 days, and I couldn't say that we completely enjoyed our trip.

Pros
+ Alberta was a very friendly and helpful host. She met us at Termini station (as a courtesy) and brought us home. All instructions were very clear.
+ The location is good: 20-25 minutes on a bus or a tram from Via del Corso and another central street. The bus from the centre stops in 3-4 minutes from the apartment, and you can get on a bus to a centre right in front of the house - very convenient.
+ The district is great: many really good hip bars, cafes and restaurants at Via del Pigneto.
+ The apartment was very clean and accurate, although it was smaller than seemed on pictures and the interior is quite basic. It shares one hall with 3 other rooms, but we never met anyone else.

Cons
- We stayed in November, and it was really cold in the apartment because of the tile floor. Thermostat helps, but it automatically turned off in night several times.
- The drain smelled really bad - it needs to be cleaned.
- The bed is big, but in reality there are 2 separate mattresses.
- During our last night there was no hot water in the apartment.
- THE NOISE! The street with pretty active traffic - including buses and garbage trucks - is right under the window, which is quite thin. You can literally hear everything! It's really hard to sleep.

Conclusion
Alberta is a great host, the location and general quality are very good, although I would recommend the apartment only if you are 100% sure you will be able to cope with noise.
