We stayed in Rigo and Raisa's casa our three first nights in Cuba, and it was without a doubt the most enjoyable place we lived during our two weeks in the country. And we stayed at really good houses in the other cities we went to. We were staying there our last two nights in Cuba as well, and couldn't wait to get back.
The casa is perfectly situated between Habana Vieja, the old city, and Vedado, a more modern part. They have two rooms, both very nice and with private bathrooms with hot and cold water. Cleaned every day, good air-condition and a fridge filled with water and beer.
The best part with this casa is, however, Rigo himself. Definitely one of the nicest guys we've ever met. He helps with everything, and is not bothered by it at all! After consulting with him, we changed our travel plans a bit, and did not regret it at all. He called all the casas we were staying with in the other cities to make them pick us up at the bus station, bought bus tickets for us in advance so we were certain to get seats, did our laundry, made breakfast in the middle of the night, arranged taxis whenever and wherever we wanted to go, always giving us good advice on what to do in Havana (and other places). We wish we could speak spanish so we could communicate better with his family as well, but Rigo speaks perfect english.
We could mention a lot of things, such as when he suddenly popped up with free mojitos when we were sitting on his balcony reading, lending us his snorkeling gear when we were going to the beach (as well as giving us a LOT of rum), and in general just being a really nice and funny guy who makes you feel at home. You will never regret staying here.
