Massimo's place was in a truly amazing location - you can hear the Trevi fountain from his apartment and see it from his window. The apartment itself however was very small and drafty and cold.
The toilet was difficult to flush and he did respond and gave us instructions which worked and the toilet did eventually flush. The shower did not drain well and the hot water did not last. After one shower the water was lukewarm then frigidly cold.
We only stayed one night and we were more concerned about the toilet flushing than the cold apartment and water so we only contacted Massimo about that issue and did not address the heat or the shower.
