The rooms are great - I love the layout (although some of my colleagues hate it - its a bit like marmite!) The beds are super comfortable, its quiet and I always get a good night's sleep.
The gym is fine if a little sparse but the sauna facilities are great.
The service is excellent - I always get welcomed back and the staff are friendly and responsive.
If internet were included on the room rate or I could have it added to the bill then I might consider 5 stars - as it is the internet service does not provide a receipt if you login using the English site, making it really hard to claim expenses, using the German site lets you get a receipt if this is important.More
