The B&B is nicely situated in Central Havana, midway between the Vedado (known for its night-life), and Havana Vieja (great area to walk around during the day). Rooms have clean private bathrooms. There are two-three shared Wifi networks -- a great thing in Cuba, since you can share the costs of the ETECSA card with other tourists. We also enjoyed the possibility of choosing among three breakfast options, from 3CUC/person (includes coffee and bread with marmelade, which was more than enough for us), to 5CUC/person (full breakfast, with freshly-pressed fruit juice and fried eggs).
The bartender, Gabrielle, also helped us check in when we arrived; he was very welcoming, and spent the better part of an hour giving us a crash course in the Cuban way of life and shared with us a printed map with some of the essentials (ETECSA cards, CADECA money exchange, nice bars and restaurants etc).
