Hugo's flat could not have been in a better location. It was a short walk to downtown stores and restaurants, close to information center, trams, busses, trains and ferry's. I found it a bit difficult to find the first time, but that was probably due to me not understanding the small winding streets on the castle hill.
If you are going to spend a few days in Lisbon.....this is a great place. Well worth the money. I would definitely go back
