Clean, quiet, air-conditioning, fridge, flat-tv, hot water, wireless internet, own back-up generator (and it's Ghana, you need that)
Medium breakfast if the food is made by the woman-cook. Different and good if it's made by the guy.
Very good location, in OSU, close to many european restaurants, clubs.
Conclusion: if you are on first time in Africa and you went only to 3+ stars hotels, and you have money, don't choose this. If you look for a budget place, clean decent place, Joska Lodge is ok.
