The key advantages of the apartment is its location. 2 minutes by foot for the beach and around 10 for the city center. We stayed in Rethimno for a week and studied the town pretty vell, thus I could for sure say that it's the best place.
Chrysa is a very hospitable hostess. Her parents live at the same floor and in case any problem you could ask them for help. For us it was just once, but Chrysa's mother helps us a lot.
