We stayed at this appartment for 3 nights. It's in a great location as it's close to everything interesting (you can go by foot to almost all attractions!). However you must make sure that you don't have a late check-in or an early check-out because in each case you get to pay 50€ on top of the initial price. As we had to leave early we paid almost 100€ per night and in that case it's not worth it because with that money you can stay at a hotel (it's the same size as a hotel room) where you will have a nice bed and you can actually sleep at nights (because of the noisy neighbors upstairs we were practically sleepless for 3 nights). Bottom line, if you pay the initial price, it is quite low and worth it, otherwise make sure to book a nice hotel room.
