This summer, together with my parents we went to the Crimea to have a rest by the sea. We stayed in a nice hotel in Kerch for two weeks. It wasn't only a swimming and relaxing holiday. We also went on many excursions. The climate was mild, scenery was picturesque and there was many historic monuments.
We never used to use a guide, because our friends told us about the places of interest to us.
I can't single out my best vacation because thanks to my family ever vacation was better than the previous ones. The worst vacation was two years ago. At that time we moved to Moscow. I had to say goodbye to many friends.
