The hotel was clean and organized, and the location was good. You can easily get to Metro and Tram from the hotel.
However, I found the hotel to be very noisy night time, we experienced that music was playing outside, and we were not able to sleep...When I asked the staff in the hotel to change our room, they were nice enough to change it, but there was still a loud noise coming from outside.
And we found the break-fast to be averaged. Most of the items were cheese and vegetables...Not varieties of food, we noticed the same items pretty much everyday.
We stayed in a 3*** hotel for a week before Mosaic, and the break-fast was actually better than Mosaic hotel.
