Great location, you can reach most of the attractions within a 20min walk our by bus/metro. Construction site outside the window was a bit noisy sometimes, but we were warned before and they never started before 9 in the morning, so it was no problem for us, as we were in the city for the most of the day.
We had a great stay there, check-in/-out and the luggage deposit worked perfectly, the appartment was very nice and clean.
