Both Friedolin and his flatmate Jakob are very nice! Our Check-in time was later than expected due to travel, but Friedolin was very accommodating. He also shares very excellent information before your arrival. The bed is big enough that two people can comfortably sleep and never touch, highly recommended for friends travelling together! The area around the apartment is very walkable, easy to get to the museum Quarter and more, but if that is not your thing the public transport in Vienna is also easily accessed. All around lovely place to stay!
