Diogo's place was big and spacious for multiple persons so when I and my spouse spent there four nights just the two of us, it was more than we needed - in a positive way. The place is not shining new but there's everything you might need during your stay in Lisbon. It is close enough that you can walk to Botanical garden, Center of Lisbon or the 'old town'. If you travel by car, the parking space might be tricky to find (from the streets, but there is a parking hall near, tho it costs about 19€ per day) so it was nice that the restaurant's employees offered to help us park on their place. Also we got some free food from the restaurant on the first evening when we were tired and hungry after our flight! Just remember to take your earplugs with you, as I noted, there is a restaurant, so at least on weekends it might get loud if you're trying to go to sleep before midnight. The traffic's noise from the alley below carries easily to the apartment too. Light sleepers; keep this in mind. Otherwise our stay at Diogo's was great.
