I have been to too many cities in Europe, and to be honest, I would say there is no city like Baku. It has antiquity and at the same time modernity, that gives a pleasant stay in Baku. The Walled City is just amazing, I would compare it with Mdina, one of the beatiful cities in Malta. Just the bad thing is, in the old part of the city, there are some embassies that are built which destroys the antiquity. Besides that, everything is perfect. of course do not forget to visit the romantic atmosphere of Baku Boulevard at night.
If you see own time and you want stay here.
