Stop looking and book this place. Stefano is a very kind and hospitable host that will make you feel right at home. He also left us good breakfast foods (yogurt, juice, bread, jams, nutella, cereal cookies, cherries, and water).
Extremely comfortable apartment and very clean. The pictures don't do it justice. It's very spacious and well taken care of. We were two but the apartment could easily fit 6. It has everything you would need and a good shower with good water pressure, and very good A/C.
Beds were very comfortable and there is a nice couch and seating area with a well working TV. Not many channels in English but you can change the language on some of them to English. Wifi also works very strong so you can always tap into Netflix.
The location is about 10 min on foot from the train station. Be aware that the roads are basically cobblestone all the way with some slight uphill inclines so bringing a lot of luggage will be tricky. We had one large bag and one carry on and had it not been for my 6'6 foot boyfriend that would have been one doozy of a walk to the apartment. However, we used maps on our phone with gps to guide us to the apartment so we had no problem at all finding it but it may also be a bit of a challenge finding it if you are not using a gps because the streets don't all have easy to find street signs.
Finally the location of the apartment itself is ideal for sightseeing. We were able to walk everywhere, from the marina to the castle sant elmo with no problems at all. Stefano has an amazing map that tells you where everything is plus suggestions for where to eat. No research is required ahead of time, it's all taken care of for you. It's quite brilliant I wish more Air bnb's would do the same.
FYI - the apartment is right around the corner from the Eat Pray Love pizza place and from a famous fried pizza place. We had both and both were awesome!!
