The location was great. Unfortunately a bit pricey, very narrow stairways and corridors. The accommodation had two WCs, one in the suite and the other one we shared between us but was really small (not really possible to stand). Three showers total, which was great. Aircon in all rooms.
The check-in and check-out was very easy. Me and my friends (5 in total) found it very practical to stay there.
The description can be a bit misleading at first, we double checked about a deposit but after the reservation was made and the stay paid, in the 3th email or so I'd to register my credit card for concluding the reservation (deposit). So you'll need your credit card even after paying the total. For 2 nights the amount was around 1000€. They register your credit card so if you do something wrong they can get back to you but the money wasn't taken not even marked on the credit card. Just respect the house rules.
