The location was very close to the restaurants on Cais de Gaia and about a 10 minute walk to get to the side via the Ponte Luis I. Obviously there is no elevator but that’s true of 99.99999% of buildings in Portugal. Also, the apartment was clean and had a washing machine. There is a wash line outside one of the windows to dry your clothes, though you can also use the self service laundromat across the street. CityLockers has a location about 5-10 minutes away next to the Yeatman hotel (CityLockers.pt).
The bad part: Check in is at 4 pm and check out at 11. I suspect the outfit has multiple buildings and only one cleaning crew. Whatever the reason, it’s pretty inconvenient. Also, there were a number of minor broken items in the apartment: the shower shelf was hanging at an angle, the opening mechanism on the big cupboard was broken (I had to open the door by sticking my hand under it and opening manually). The AC/heater was broken, though they did provide a portable heater that was adequate. Of all of the above, the shower shelf was probably the most annoying because my bath stuff kept sliding down.
