Hi Vincente welcome to FT.
Vienna will be a pefect match for you. It is our favourite European city and we visit often - and happen to be there now.
I have no first hand experience of Gay life in Vienna but I have no doubt it isn't a problem. There's a vibrant gay scene here.
The city retains lots of old fashion charm and manners. You'll rarely hear a car horn for example and if you walk off the pavement you won't. be run over .... Until a few years ago teenagers would stand up on busses and trains for older people to sit .... but that has changed a little.
I suggest you make your first two bar visits to Bettelstudent (poor student) for a drink and a set lunch and perhaps Kuchldragoner ... the owner Ronald is gay and will give you pointers to Vienna life. Cafe Einstein is staffed with music students and their badges tell you what instruments they play. There is extraordinary art and music in Vienna ... it is knitted into life.
You will love Viennese life - I have no doubt.
Enjoy your time in Vienna.
Oh, that sounds really nice. I find really interesting the city is still retaining its old charm. That is why I like so much Europe. I have seen some photographs of the city and the architecture looks stunning and romantic. By the way, I have been told Vienna is one of the best preserved cities in Europe because it was not very affected by wars, like Berlin for example.
I think gay life should be okay, at least. I just wanted to receive some feedback from people who had already gone to the city and have experienced the feeling. I will go to those two bars and ask for a drink for sure.
Too bad I still have to wait two months and half to arrive in Vienna.

Can't be more excited! It looks pretty cool!

Can't wait!!!!!!!!
Kind regards,
Vicente
