I would not recommend staying here. We had 2 major issues during our stay. While Guglielmo did his best to address our complaints, it took nearly 2.5 weeks for them to be resolved.
Major Issues:
1) There is not "wi-fi" in the apartment. Instead, Guglielmo has provided a mobile hotspot with a data cap. The hotspot does not get good reception in the apartment and is very slow. We raised this issue with Guglielmo, and during our stay he twice said an internet provider was coming to run a fixed line internet connection to the apartment (we stayed 6 weeks). The provider either didn't show up or when he did show up he wasn't able to run a fixed line, so we were stuck using the hot spot. When we pointed out it didn't work, Guglielmo did eventually provide a hotspot that got better reception (~2.5 weeks into our stay) after we said we were going to leave and ask for a refund. However when we hit the data cap on this hotspot he wasn't able to provide any more data and we had to use old hotspot with limited connectivity.
2) The showers in both bathrooms flooded the bathroom floor when used because they didn't drain. We were told this when we checked in, but we were also promised a plumber would come fix the issue the next day. The plumber never showed up, and it took 2.5 weeks for a plumber to come and snake the drains.
Beyond these issues the apartment was mediocre, but adequate for our stay. In general the furniture is not particularly comfortable (as noted in the post), the apartment was somewhat dusty when we arrived, and the kitchen sink being outside proved to be a bit annoying. Location was great and the views from the balcony were nice.
