Bremen, probable among the most attractive old cities in Europe. Uniqueness of old streets and work of artisans makes your hair (if you have them) stand on end.
Prague, combinaton of narrow streets, people from alsmost all nationalities, anciety buildings and in particular the palace are unforgatable moments
Zanzibar stone town, it is among the oldest town in East Africa. Narrow streets, old houses and forts are attractive features you will see in this town
Probable among most expensive hotels in Lagos but very nice, I spent 5 days there while attending a meeting
