Diogo's place is perfect in terms of location.... there are many shops, restaurants, and attractions that are right in the immediate vicinity. We were not really there for sightseeing (as we've been to Lisbon many times before), but this would be a great jump off point for anyone who is trying to stay in a central location to see the city. The apartment was clean and well appointed - Francisco was there to greet us when we arrived and it was a very easy check-in. Wifi also worked well which is always a bonus! All in all a great place to stay
