The jewel of Havana is La Habana Vieja or Old Havana. This area has been totally redone is a great walking area. It is has been an UNESCO World Heritage site since 1982. There are hotels, cafes and restaurants in this compact area.
Have a Mojito at the rooftop bar at the Hotel Ambos Mundos at Osbispo No. 153. This was Ernest Hemingway’s Havana hideout. The views are great.
There are booksellers around the Plaza de Armes where you can shop or take pictures of some of some of the well-positioned characters posing and smoking cigars for the tourists.
I also recommend drinks at La Floridita. Known for it Daiquiris that Hemingway liked, this colorful bar and restaurant still looks like Hemingway could walk right through the door.
I loved getting out early and walking the streets taking pictures of the crumbling colonial buildings as the city woke up. Late afternoon is another great time to walk and see the sites. The colorful crumbling buildings are a perfect backdrop to many of the old cars from the 1950’s which are found everywhere.
