First off, Greshma is an amazing host! Approachable, knowledgeable, and incredibly kind. The apartment is clean, newly renovated, and it is in a wonderful location in Vienna. Highly recommend staying here.
Also, if you like Indian cuisine Greshma's restaurant (which is a 45 second walk) is absolutely to die for. Literally the best Indian cuisine I have ever eaten.
10/10 HIGHLY recommend.
