Martin's house was very very cosy, and has everything you need! Wifi is strong and the room is spacious. Martin is also very friendly and even made us coffee when we first arrived! He's very knowledgeable about Vienna and gave us tips of where to go and what to buy as souvenirs! It's also very easy to head to the city as his house is within walking distance from a U4 station! 10/10 would recommend :)
