Last Saturday I stayed with my girlfriend at the Kamakura Prince Hotel, which is near the ocean. ( which is in front of sea.』はちょっと可笑しい英語と思う。which is near the ocean.』のほうがいい）The view from the hotel was so great. 

And We ate 'the most delicious breakfast in the world' at 'Bills'. The main shop is in Australia. It is said that Tom Cruise, Leonardo DiCaprio, and many Hollywood stars like this breakfast. （「朝ご飯」じゃなくて「この朝ご飯」というのほうがいい。もっときれな英語だから。）
We had a fun time last weekend.

本当に良くできました！
