Pros: The apartment is absolutely stunning and incredibly well located. It's a fairly easy walk (minus the hills, but that's just Lisbon) to anywhere you want to go. My partner was working remotely and there's a great working space and good wifi which made it very easy for him to do so. We watched a beautiful sunset from the bedroom balconette one night. The apartment was spotlessly clean when we arrived.
Cons: Check-in was pretty bad. It seemed like the main host was traveling abroad so she wasn't there to help us. She told us to message someone else on whatsap. We messaged them more than 2 days before check in and didn't hear anything until the day of. That person could not meet us at the check-in time (3 pm) and asked if we could meet later (4:30 pm). We had just come off nearly 24 hours of traveling and just wanted to be able to put down our bags and shower. Eventually, after much negotiating, she had the cleaning lady let us in at 3:30. Additionally, the apartment was not well stocked. There was no handwash in the bathroom (just aloe gel), and only baby shampoo in the shower. There was no laundry detergent for the washer. Ultimately, we ended up going out and picking some of these things up. We had messaged the host but didn't hear back from her for well over a day and needed to do laundry.
