Lovely hostess, very caring. Makes sure that you are alert to possible scammers and will point you to where you can change your USD at the right rate.
Beds good, usual good breakfast. Clean filtered drinking water free from the fridge. Breakfast area nice and cool in the heat.
Location central in Havana in what looks a rundown, yet very safe, area about 20 minutes walk, or a USD10 taxi ride from the Capitol.
Restaurant round the corner where the locals eat, provided very good and cheap evening meals.
Good value, even after allowing for breakfast on top and taxi rides to the Capitol area.
TIP: make sure you bring soap, which must be in short supply in Cuba, as it is not provided, like in most of the Casas Particulares that we stayed in.
Wifi is available, at a cost, but you need to ask for it and be prepared to pay for it (I don't think that it is expensive).
Final point: stay here rather than a hotel to meet real locals. At least this way your money will go to the locals rather than funding the lifestyles of the incompetent politicians. Also the food will be fresh and not re-used as is commonly the case in hotels, apparently.
