Goia's place is super comfortable, nice and clean. It is the place where you can really relax after an intense city tour. It's about 20 min by tram from the Opera. If you plan to get there by car I can highly recommend to leave it during your stay in APCOA underground park at Weinheimergasse 4 for 6€ per day. If you plan to stay for few days in Vienna search no longer!
