Excellent location - this was the best pleasant surprise; from here it seems everything in the city center is within walking distance, and I love to walk. Mostly fully equipped kitchen (wine and bottle opener? YES!). Bed comfortable. Apartment comfortable. Guest sofa-bed comfortable. There was some street noise during the day and early night being adjacent to the trolley line (28! :-) ), but after 10 or so the noise dropped off considerably. What it lacks: functioning AC (the humidity in the apartment was oppressive, I could not sleep at night. There seems to be a heavy mist that comes off the river); no iron and ironing board; it needs clean-smelling towels, and clean sheets and pillow case for the guest bed. The towels smelled of mold or of the previous use and the guest sheets and pillow case were dirty/used ...yuk!; needs a fully-functioning coffee (espresso) machine - the coffee came out lukewarm; the apartment needs a very good cleaning, especially the rug in front of the television.
We only received one key to the apartment - request two. I got locked out and the owner came within 30 minutes on a Tuesday night, which was great service and highly appreciated. But the Internet works slow in that part of Lisbon and it took me almost 90 minutes to reach the landlord through AirBNB (the contact number was in the apartment).
Next to the apartment's building is the Nova Wine Bar - perhaps the best amenity - owner Ricardo is extremely kind and friendly, his food is very good (try the octopus!) and some of the best tasting wines that I have ever tried. He knows how to choose the wine to please the customer's palate.
