We stayed at the Hotel Johann for three nights at the end of September. We had an enormous room (304), and loved everything about it. Really lovely bath! Breakfast was as everyone else has said - very fresh, lots of variety, and altogether delicious. The staff are absolutely lovely, and so helpful! On our first night, we were too tired to go far, and so asked the receptionist if she could recommend somewhere very near. She suggested the restaurant in the little park (out the front door, turn left, cross over the road, and go into the park!). We had a wonderful meal there, and would have cheerfully eaten there every night but felt that we should be a bit more adventurous. I'd booked a boat cruise with dinner for our last evening, and had to show a voucher - I took my i-pad down to reception and asked if they could print it for me, if I emailed it to the hotel - absolutely no problem (I got charged £5.00 in London for this before). It is in a very good location - nice and residential, which we liked very much, but close to about three U-bahn stations. I can thoroughly recommend the hotel and would love to go back there next time!
