Staying at Sven's place was a good choice. Me and my boyfriend liked the vibe of the place, quite simple but stylish. We haven't met Sven, but he replied very quickly to our messages making sure that we have everything we need. The apartment is located in the center of Palermo, which was very convenient. I would recommend this place to everyone who wants to visit Palermo, but please keep in mind that it's located just next to the La Vucciria market so during weekends it can be very noisy. Just bring earplugs and you won't regret it :)
