Was recently in Bratislava with a friend and we ended up at Floratours, which is very close to the city centre. The lady there (Isabella) was absolutely lovely, as were all her staff. She got us set up with a city tour on a miniature train and also organised tickets for us back to Vienna on the Twin City Liner. Everyone spoke beautiful English and they were really keen for us to get the most out of our visit to their beautiful city. If I was in Bratislava again and had time to explore the rest of the country, Floratours is definitely where I would go to make the arrangements. Would absolutely recommend to others!
