Casa Carlita is a casa particular with the feel of a B&B - a set of three guest rooms with an immaculate shared bathroom.
The casa is located right next to Havana University and within a short walk of Havana Libre and The Nacional, two big hotels where you can change money, hire a car, book excursions or top up on food/drink.
The Casa offers good food whenever you want it, though it is located in the Vedado area, which also has a range of alternatives. Vedado is supposedly great for nightclubs, though we hit it while jetlagged on a Monday, so can't vouch for this.
It is a 30 minute walk (or $2-4 taxi ride) along the Malecon (sea wall) to Old Havana. We stayed in Old Havana later in our trip but would be happy to stay in Vedado again.
This was a great first stop on our tour of Cuba. It was also good value. I would recommend it wholeheartedly.
