This apartment is as beautiful as it looks, and in as prime of a location as it says. It was a great place to stay and would recommend it with two caveats: you must be able to deal with the hot weather in the summertime because there is no air conditioner (accurately listed in the post), and you must be able to sleep on a firm mattress. Outside of that, there were no complaints other than our tough check-in process.
Our complimentary ride from the airport (a great plus!) arrived 45 minutes late. That was tough to handle because we had already agreed to wait 4.5 hours after our overnight plane arrived at 6am (the initial wait was well understood by us). After finally being picked up, we were allowed to fully check in by the host’s representative. It wasn’t until that rep left that we realized the place had not been cleaned at all from the previous stay (terribly filthy sheets, dirty towels in the bathroom, trash, cigarettes, etc). We were set to climb into bed for a well-needed nap when we made this realization. The rep came back and changed the sheets for us and asked when we wanted the cleaning service to come. This was at noon. We said 4pm so we could nap for a bit before getting ready to head out and explore. We were awoken at 3pm by the cleaning service team entering the apartment while we were sleeping in bed, which you might imagine is a frightening way to be woken up - and early - in a brand-new city. I could not communicate with the service member because she did not speak English, so I just grabbed towels from her and that was that.
Overall, the apartment was very nice, but that check-in process unfortunately ruined the first day of our brief two-day stay in Lisbon.
