Great experience and highly recommended!
I stayed at Abraham's house with my colleagues during the conference so we went there as "AirBNB business travel" and got appropriate bill for economics department.
Our stay was just perfect, Abraham was very kind, friendly, helpful and flexible. He welcomed us warmly, offered us plenty of fruits, cereals, good coffee, tea, milk and other things for free and he was asking us during our stay if we have everything and if everything is fine. He enabled us wash the clothes, wi-fi connection was very good so we had just everything we wanted. Portland is great city for cycling so I was using one of his two fix-gear bikes which he offers with helmets, lights, tools, locks and pump for free and enjoyed Portland at its best. We got also maps and tips for hikes, good restaurants, etc.
The house is very nice, comfortable, spacious and clean with its history and style. Food store is close, it's in nice and calm location on the yellow MAX tram so it's very available, just 15 minutes to Convention Center and few more to the city center.
After our stay Abraham took us to the airport by car.
It was my first experience with AirBNB and it surpassed my expectation.
I recommend it to everybody, house is suitable for business travel but I can well imagine to be there with my family or friends. Hope I will come back!
