In short, you should stay here.
Perfect location, 10-15 minutes walk from pretty much everything. Daytime it's great for sightseeing, night time it's great for eating and drinking
Clean and roomy apartment. 2 bathrooms made things a breeze. Soft and comfortable beds, perfect for sleeping off far too much red wine and pizza.
Christian helped organise transfers to and from the airport which I would recommend so that you can arrive with no fuss.
