I went to Budapest because Art Nouveau and Secessionist design is a love of mine. So the first thing I did was look for a specific tour for that. I enjoyed it and would just improve a couple of things. Stick more to discussing elements of design and talk about general country history in a short format when it affects design. Don't stop for refreshment, I would rather use the time to see more. Use up the entire 3 hours and offer an extension at the end beyond the tour guide's own apartment. For someone that loves the style of this city, this tour is a wonderful use of time.
Sorry for the belated answer. Thanks a lot for your expert recommendations, we'll do our best to perfect the tour. However, most people enjoy a short break, especially at the Café called Art Nouveau furnished with relics from the time of the Fin de siécle. The house where our company's, Fungarian's, office is was built in 1898 and an excellent site to understand what Art Nouveau meant in practice when it comes to residential buildings. The greatest artist of Art Nouveau stained glass windows is Miksa Róth, whose works can be seen in the Parliament and several public buildings with no access for the public. I thought that a beautiful piece of his could be of interest for art lovers. I hope you will visit again and see more of the numerous Art Nouveau buildings. Best, Miklós
