POSITIVE: The apartment was small but comfy. We had everything we needed for a comfortable stay. Also they were very accommodating with regards to earlier check-in and we also requested a scale to weigh our bags which they organized for us.
NEGATIVE: the listing includes parking which is definitely inaccurate. We got told to park in the street and nearby areas, which resulted in our car getting towed and wasting our one day available in Lisbon. So, don't book this apartment if you have a car. If you don't have a car, the place is perfect, just low ceiling (max 6ft).
