Check in process was very tedious if you are arriving late, there is additional charge, unless you go with their taxi arrangement — which always claim “25-30 euros” when Uber can get you there for <$15. Seems like a way to rip off tourists. I do not understand why they do not use number lockbox and allow guests to check in. Maybe it’s because it’s in Alfama? But the place felt extremely small, hard to even use bathroom or take a shower. Overall, if you are charging USD, and expect tourist-associated price increase then the provided service should reflect the “american standards”, which this place does not provide.
Overall, if you are coming with friend, maybe good for a few nights of stay. Otherwise, I’d rather look into hostels as there are plenty of hostels around in Lisbon with much better accommodations, and probably help out the locals as Airbnb properties are essentially pricing out the locals. Alternatively, just rent a hotel as price is not that much different.
