We had a great stay at Modi's apartment. It is a 2-minute walk from Piazza Santo Spirito and close to the city centre as well. We had a problem with the water the first night and Modi was really helpful in getting it fixed immediately. Everything was clean and ready for us when we arrived. His instructions and recommendations were very clear. The only downside is that it can be a bit noisy from the street if you're a light sleeper.
