This is a beautiful apartment in a bustling, active part of town, within walking distance of the most popular places to visit in Lisbon. The apartment is right off a big commercial street (with shopping like Pull & Bear and similar), so be aware that you are right in the middle of the action of a busy capital! There is a bit of ambient noise throughout as a result - traffic passing, etc., but nothing that would keep you up at night, but be aware in case you're sensitive to noises. When we were in the apartment, we found there was no shampoo or bath gel (these are listed as amenities in the listing), and the hand soap dispenser in the bathroom was empty. I let the property's owner know, but was told shampoo and bath gel weren't part of the accommodation and the hand soap dispenser should be there (it was, but empty inside). I didn't want to kick up an argument while on holiday so I just went and got some myself.
The big walk up the stairs was a bit off-putting when hot, but as others have written, there was air conditioning in the apartment which was super nice to have. Big nice kitchen and good balcony for sitting out with a book.
