I would suggest avoiding this place. The only positive attribute that I can provide is this rental's location. It is one street over from the main road in Lisbon.
The negatives. The street is still loud at night and since the blackout roll down shades are broken, you cannot block out the street lights in the main bedroom.
There is no lift and the stairs are uneven and dangerous. Lugging suitcases up the stairs was treacherous and down was even worse. Portugal considers the ground floor to be "0" so this apartment is actually on the 4th, not 3rd floor.
The shower in this apartment is deplorable. There is so much mold on all of the grout that it is absolutely disgusting. The shower floor is warped and therefore causes the water to pool and leak all over the bathroom floor.
During our stay we had to request extra towels to mop up the bathroom floor and we were not provided the listed soap and shampoo until the third day of our 4 night reservation. The overall cleanliness of the kitchen was subpar. I would never want to cook in a unit like this.
Communication with "the host" if you can call them that was minimal at best. They simply wanted to take your money and run. Find somewhere else to stay.
