Check in and out required going to two different locations to pick up the keys (easy process and fairly close by) but definitely have to factor in especially when you have luggage. There are 120 steps up to the flat but we even managed it in 36 degree heat and I can assure you, it's worth it for the views at the top. As already mentioned by many others - the view is absolutely incredible, even better than the pictures suggest - we ended up spending a lot of time on the balcony because it was so spectacular. Location is absolutely amazing and was very quiet when we were there. Flat is well equipped with lots of kitchenware and cooking things etc but maybe not all as clean as could be. Shower was lovely and powerful which we were surprised at for being so high up! Damien was very responsive to all messages.
