My three-year old daughter and I stayed at the Multnomah Village Studio for five nights and it was perfect. The studio is private, and in a very quiet neighborhood. Lots of cute shops and great restaurants are just a few blocks away, and there are great trails for jogging and parks for playing too. Nick gave us really clear directions for how to get to the place and how to get in, and he and his adorable family came up to welcome us a few hours after we arrived.
We would definitely stay here again the next time we're in Portland. It's a great spot!
