We spent 4 nights in the red house and really enjoyed it.
The apartment is well equipped, the kitchenette is suitable for cooking a small dinner. The bathroom is nice and a washing machine is available for the guests on the corridor. The three apartments have a common corridor, but we've never met other guests during our stay. Wifi worked well.
Location of the house is good, there is very good public transport connection with the city centre (buses 81, 810) and Termini station (bus 105, trams 5 and 14).
There some supermarkets in walking distance and there is a bigger one (Despar) in 15 minutes walking distance or 2 bus stations.
Alberta is a super friendly, very helpful owner, she did her best to share with us all information about everything.
She ensured us a pick up at Termini station , which was really great, when we arrived at midnight.
To sum up we recommended Alberta and her apartments! :)
