We stayed at Daniele's place for 2 nights and we can't say something else than it was wonderful! Castelmola is a bit difficult to access because it is up on a hill with very tiny and curvy streets and roads. The view is beautiful and breathtaking though.
There is a natural path to walk from Castelmola to Taormina in 20-30 minutes. We recommend to go to the beach "Sant' Alessio" which is 10km away. There are some few nice restaurants in Castelmola not far from the accommodation - but Daniele has a lot of information about Castelmola too.
Ver nice communication and everything you need in that beautiful and brand new apartment. We recommend it highly. Grazie Daniele.
