The apartment was larger than expected and was very clean. It was filly equipped with everything that would be needed for a short break and the washing machine works! All sheets and towels were also provided in a large variety!
There were, however, some downsides. The downstairs, where the double bed is, is very damp in spite of a dehumidifier being kept on constantly. My boyfriend suffers from asthma and so was unable to sleep down there as he experienced breathing difficulties. Instead he slept on the fold out sofa bed which was easy to use.
Another fairly significant problem was the mosquito nets that are fitted to the windows, as they do not provide complete cover. This meant that during the evening and night we were not able to have the windows open without letting in a lot of mosquitos. This led to the apartment getting extremely hot and humid in the night time, to the extent that we were not able to sleep well. There is a light fan but at the highest power it was ineffectual.
The apartment is about a 20-25 minute walk from the duomo. There is a bus service but we found on 4 occasions that the bus was either 30 minutes late or did not arrive at all! For a short visit the walk is fine though. The neighbourhood is very nice, with a coop 4 minutes walk away and a gluten free bakery opposite which we highly recommend!
