We just spent a week in Manuel's well appointed apartment and really loved it. The location is great and the neighborhood offers a lot if you explore.
(Try Frei Contente for a great €9 lunch, Foxtrot for a fancy & pricey cocktail, and Trivial for a late inexpensive dinner. If you are gay, this apartment is super close to all the good Lisbon gay bars. Use Uber to get to Bairro Alto €2.5 and the airport €9 - €12.)
Check-in and communication were excellent. We had no issues at all during our stay. Everything functioned and Manuel explained everything.
Comfortable bed, nice linens, great rain head shower and well lit bathroom, great Nepresso Coffee Machine (a few coffee pods were provided. You can buy a box at the Mini Preco down the block.)
We had service mid-week for new sheets and towels and light housekeeping. This was a first for us and it was greatly appreciated. There is also a fire extinguisher, first aid kit, and emergency phone number sheet.
I can highly recommend this apartment. The small terrace is a plus during the nice weather.
