Ali and David were great hosts and the accommodations were very nice. David met us at the house to give us our keys, show us around and tell us about the bikes we'd be able to lend. Ali and David checked in with us whenever they saw us to make sure our needs were being met. They lent us bikes and helmets and told us of good routes to take to get to various parts of the city. When we couldn't find a taxi to take us to the wedding we were to attend, Ali insisted on giving us a ride. And when we were leaving to grab a taxi at the nearby Kennedy School (because they had warned us about Parkways and the blocked streets), they ran in the rain to get back in time to send us off with a nice farewell! It was a lovely stay and I would recommend staying with Ali and David to anyone considering a visit to Portland.
