Ricardo's place was great for us, it is well equipped and makes for an easy stay in the city, you can make a home of it or keep out all day.
We didn't not meet Ricardo but communication was easy and he let us check in earlier which helped us tremendousl.
The only downside to the place is that it is quite small and there are windows on one front, but that seems to be the case in many places in Lisbon.
All in all a great experience and we will be back.
