Wow! I have stayed at several AirBnbs now, and this location is a must if you want to be central in Lisbon. You can walk to most popular destinations, many wonderful restaurants, bars, and the Metro. Although it is very close to popular nightlife options, the location itself is situated on a very short and quiet street, in a safe, secure and quiet building.
The host, Tiago, was the best I have encountered! He kindly met me around 21:00h as I hate a late flight arrival. He showed me all of the features of the condo, and provided me with suggestions on food. He also provided me with several maps and guides on the local area. He made himself available to questions, and was very responsive.
The condo itself has a very comfortable bed, which can accommodate two persons. I am fairly tall (1.85 m) and the bed was great. The unit also had two portable heaters, as Lisbon can be cold at night. Both heaters were more than adequate for the living spaces. The kitchen has a small refrigerator, dishwasher, coffee maker, stove, and toaster. Everything was fairly new and worked great. I also appreciated having a washer/dryer, along with enough detergent to wash clothes during my stay.
The television had a variety of English and Portuguese options, along with Netflix. The WiFi was great and the internet connection was reliable.
I hesitate to give this flat such a good review, because I would like to be able to use it in the future. It was truly wonderful, and I look forward to returning in the future. Tiago is an amazing host! One of the best I have encountered!!
