We were comfortable and happy in Pãolo's apartment. There's a strong 4G signal there via Vodaphone and we liked the quiet building, the location, and the neighborhood. It's easy to get around Lisbon via public transit and the garage (which we didn't use) makes it possible to have a car (which we didn't). Which is good, the parking in Lisbon looks difficult.
Pãolo was considerate and easy to deal with, and getting the key was a snap with the building security.
Lisbon is different from a lot of places in that the local markets have great wines but are short on good produce - local or otherwise. Even at central markets. May be somewhat time-of-the-year related, but I suspect that a lot of people eat out.
