Small hotel , many guest , room is nice but is not soundproof.,in the morning the housekeeping made sound outside already .. breakfast is good but very crowded, I wait there 15mins to find a table, the service very busy like battle , and full of people,even it is a nice restaurant, I can’t enjoy it much , feel anxiety . Swimming pool is just for taking pictures, extremely small and full of guest . There is no electric kettle in the room. front desk is not professional, I want put some food in fridge after check out they refused . The restaurant downstairs is beautiful but food is so so, no expectations for food in Vienna .If you want privacy and spacious will be disappointed in hot season
