The flat is great for the price point. It is well located close to the metro, busses and trams. There are many good restaurants near by. The neighborhood is quiet and a little outside the more rowdy areas.
Pros:
Location, walkable to many great areas and a block away from public transport.
Safe, Lisbon is a very safe city so most places are very safe.
Well decorated, light and bright.
Well appointed, it has everything a traveler will need.
Communication, great communication and help from the host.
Cons:
Size, it is very small and not suitable for four people in my opinion. It is fine with two. The bathroom is small. If you are sharing a bed the space is good. With both beds in use the space is cramped.
Noise, the flat is directly on the street and you can here everything; however, with the exception of Saturday night, it is very quiet between 10pm and 9am. On Saturday night you can avoid this problem by by our in the town, like everyone else in Lisbon. Weirdly, the trash was collected after midnight on a Saturday.
Amenities, the flat has everything you need, really. I have stayed at many AirBnB’s, and it probably differs by city or country, but a few extras (milk, wine, bread), are usually a welcome surprise. I know it is not expected but it is also nice not to have to go to the grocery immediately.
Keys, this is my only real problem. We were only given one key to use. This is very problematic. If you are planning on staying here and you are with someone that you will not but with all of the time ask if they can provide another key.
Overall,a great place for the price.
