We stayed for three nights in Piran. The accomodation is very very basic, but if you don't mind having a not well equipped kitchen, a blocked shower drain sometimes or a very small fan and no aircon, than you will have a great time there. The host Anja is very nice, she helped us a lot. The location of the guesthouse is 15mins steep walk to the city center and to the beach. All in one, we liked it there - but we also don't mind having a basic accomodation - so it really depends on your expectations! Also Anjy told us, she will be renovating all rooms during the next years.
