I have spent 11 days in Johanson's flat with one friend and it was just amazing. The view on the Tagus is awesome and the neighborhood is great. You can walk alongside the Tagus, just chill in small parks and enjoy the different monuments built for 1998 universal expo and the relaxing landscape. Just the perfect spot for walk or run addicts.
The flat is very convenient and well equipped. We have not faced any technical issues (Wifi works perfectly). The flat is bigger than what it looks on the pictures. Outsides noises (cars mainly) are well blocked when windows are closed.
You have supermarkets at 5 and 3 minutes walk (Lidl and Pango Doce) and a big mall at around 10 minutes (the shops and food places close at midnight there!). The proximity to one of the main train station (Oriente) is a plus (also at 10 minutes walk). You can get trains and metros to go anywhere in Lisboa and also to Sintra. Taxis are also available there.
Johanson was very reactive for any questions we had when organizing our trip. He could not be there to give us the keys but his friend Ricardo was very kind and helpful. He has waited for us as our plane was delayed for more or less one hour. He remains available for us all our stay long. We could have returned the keys later on the last day (our plane was at 08.00 pm).

A great first AIRBNB experience thanks to Johanson and Ricardo. I can only recommand you to give it a try. Good place to stay to enjoy a trip in a wonderful city.

Johanson, we will be back for sure!
