Casinha was a great host. She contacted me when we got to the flat to make sure everything was okay, and checked up on how things were going every once in a while throughout our stay. She had written, detailed instructions on the front door. She was very available for questions, and was genuinely concerned about our comfort.
The flat itself is in a great older neighborhood of Anjos, with little cafés and convenience stores. The flat is above a very tasty pizza place, Pizza Retrogusto, which Casinha recommended. It is also very close to various metro and tram stops, including the tram 28E which is right across the street, NOT to be confused with the famous tram 28 that takes you all around Lisbon. But the 28E will take you to a stop in Martim Moniz, where many of the trams have stops, including the initial stop for the popular 28 tram (look for the long line of people--there's always a huge line for the tram 28). But be careful--halfway through the tram 28 trip, you'll hit an unannounced stop and have to swipe back in to get back onto the tram. So make sure you have an unlimited day pass, or somehow have enough credit on your pass!
Casinha wanted to make sure our stay was comfortable and up to our liking even after we'd checked out. Very invested, very helpful host. And a great location as a base near the city center.
