Alzbeta is an extremely good tourist guide. In fact, if Viator had an option to give 10 stars I would do so. She showed me Bratislava and also took me to Devin Castle. She is very experienced and knowledgeable. Furthermore, as her profile indicates she was smiling, positive and cheerful throughout the 6 hours she spent with me.
I would have no hesitation in recommending her to anyone, solo or group, looking for a tourist guide in Bratislava. You will definitely finish your tour happy.
