Cláudia's place was very nice and comfortable. Cláudia helped us with the check in procedures and answered all of our questions. The place is near a few restaurants, supermarket, and about 5-10 min walk from public transportation (for the metro, it's about 15 min or so). The place had everything we needed, and the supermarket was just about 5 minutes away walking (up a hill), so we could get purchase items for breakfast, snacks, water, etc.
You can also walk to the city center, it took us 25 minutes or so, and it was a lovely walk from the apartment. Bairro Alto is also nearby, only a 10-15 minute walk. There, you can find lots of restaurants with Fado music and extensive night life options (it is walking up a long hill, but you could probably catch public transportation or get an Uber).
Cláudia was very helpful and responsive when we had extra questions for her and our stay was wonderful.
FYI - shower was on the small side (for a big guy like myself), but managed it just fine.
