Felix has been the best host we could ever dreamt about! Felix has been very available and patient for my family and his sense of welcoming guests is just amazing (he put a bottle of champaign in the fridge and had done some shopping so that my family had stuff for breakfast the day after they arrived!).
The apartment is beautiful; perfectly located: everything is literally round the corner (public transportation; downtown; shops; grocery stores..); really clean and the beds are very comfortable! If you intend to come and spend some time in Vienna; I totally recommend you stay at Felix' ! Thank you very much, Felix; everything was perfect!
