The description of having to climb 5 flights of stair is accurate and most people have said its worth it for the views and generally we would agree. However, if you are going to stay there between June and September when the temperatures are very high you may want to think again. The apartment does have air conditioning but not like what we are used to in North America. We were there the 3rd week in June, daily outside temperatures we over 30 degrees Celsius plus humidity. The apartment never got any cooler than 24.5 degrees Celsius even though we set the a/c as high as it would go and ran it day(with blinds closed to keep sun out, so cancels the view) and night so was quite warm to try and sleep. One must decide between the charm of a quaint old small apartment and the comfort that one might be accustomed to if staying at a hotel.
Great location, walking distance to all the sites, close to lots of restaurants, cafes and shops.
