Very good stay overall, good room size and cleanliness, well appointed facilities. Breakfast was good. Didn't use the spa so can't comment on that. If you wanted a swim everyday it would be expensive. Ubahn outside.
Only 2 small faults, room cleaning didn't replenish tea and coffee and there were only 2 coffee sachets for a 3 night stay. This happens at alot of hotels, I don't know why this is so difficult to get right, it costs the hotel nothing compared to your room rate.
Second issue was with one bar tender. I had a whiskey old fashioned, he made abother staff make it and he didn't know what he was doing so the first was frequently shouting at him. Took my whiskey outside, after a while then first bar tender came out and asked my if I wanted another, I said know and he said then I should pay, I asked to charge to my room and he said I needed to come back inside, I hadn't finished my drink and was enjoying the evening but I complied. I then said I would pay immediately and so he put the card machine out, I tried to pay but then he said in a very passive aggressive manner "if you don't want to tip me you have press this button". I didn't complain but why would I tip someone who didn't make my drink, didn't serve it to me and called me inside to pay before I had finished it? This was 1 hour before close on a Saturday night so he wasn't chasing up.
This is a small irritation on an otherwise very pleasant stay but hopefully the hotel will read it and take note.
