Location is great, however if you're coming with a Taxi make sure that it stops you in the main street (and there is a stairs right next to the place) as the place is in a walking only area and you end up walking round 10min on cobblestones with luggages.
More units in the building are being rented out as well, if you're unlucky like we were, we ended up having people partying on our heads at 2am.
We stayed there 4 nights, and we needed towels to be changed but these were at a charge of round 7/9eur each. I expected to have an extra towel when sleeping more than two nights.
