Marisela is a wonderful host, I enjoyed my stay very much. For me it was important that the casa is located a few steps away from the University, but it is also close to a few nice restaurants, clubs and other landmarks in Vedado. Finding the right door is a bit tricky, go the the second floor (or the first, depending on how you conut - three flights of stairs from the entrance). Be prepared to be woken up at night by other guests returning home - you don't expect Havana to be quiet, do you? But it's very peaceful otherwise, I had no trouble falling asleep again.
