Perfect location - easy walking distance to everything you would want to do and see, from popular sites to hidden gems. Located off a main drag so the noise level is a bit muted, but can get a little noisy on Thurs/Fri/Sat nights.
There were four of us - all girls - sharing this space and it worked out well. The bathroom is generous for my usual expectations of European amenities, and the layout was conducive to hanging out and having privacy.
You'll definitely get a workout climbing the stairs on a regular basis, but in my opinion it's worth it to burn off all of the food you'll be enjoying.
