Spent just one night at Danny's but it was a pleasant and cosy stay. The check-in is seamless if you follow the advice. It's a couple of minutes walk to Naschtmarkt, the awesome market with restaurants so even if you arrive late you can still grab dinner there until around 11pm.
The subway station is 30 seconds from the building and you also have e-scooters parked outside if you feel adventurous.
