We had a nice stay at Costas apartment! He was out of town but organized a smooth check in for us with a friend. He was also attentive during our stay to any needs we had. The room is large and welcoming with a nice desk and space to hang clothing. The only downside is the bed is really quite hard, to the point of being very uncomfortable. Hopefully Costas is able to change this sometime, because otherwise he has a really nice setup that I’d recommend! His kitchen is fully equipped and we walked everywhere in Vienna. There are lots of food options and supermarkets right next to the apartment. A good value!
