The location of this Airbnb is excellent; located on a lesser busy street and within walking distance to all of downtown. Take advantage of the 'Padaria' located around the corner, best service in-town.
The check-in was not the best...after previously confirming our arrival time and knowing that the check-in is as of 2pm, we were told that our room wasn't ready and we were only expected at 5pm...not sure where this information came from, as we received a confirmation of our arrival at 2pm. Like most 'customer service' places, we were given excuses without a solution, so be prepared to provide a solution yourself.
The loft is not a loft, but a room with a very small kitchen area and basically no living-room space. If you are looking for just a place to sleep, then you will be okay. We had the top floor and the view to the castle was nice.
There is nothing offered with your room, be it a couple of coffee pods, water, the basics that I found in other Airbnb's that I have experienced in Europe. So make sure you purchase these if you want to have coffee in your apartment. However, Lisbon is filled with Cafes anve d the coffee is amazing.
If you are driving, there is an indoor parking garage at the end of the street and very close to the apartment. Hard to find a parking spot on the street.
The rate is very much comparable to a 4-star hotel in the vicinity, so you may want to review your choice for accommodation.
