Can't complain about anything. Staff was friendly, room was clean and comfortable, and breakfast buffet was a nice spread in the morning, with plenty of options for any the various diets.
I used their gym a couple times, which although was simple, there were enough free weights, bars, and a few benches and machines for put together a good workout.
The location is very quiet, but Bratislava is small, so there are plenty of public transport options and restaurants within a 5-15 minute walk.
Its a great place in a great city!
