I really can't say enough about the hospitality Erin & Havan showed me & my girlfriend. This was our first time staying in an Airbnb and it couldn't have been an easier/more comfortable experience. The space is updated and all the amenities are high quality. There was even a little "welcome to Portland" basket left for us when we arrived. We found the Hydrangea house was a great base camp, of sorts, for us. Everywhere we wanted to go inside the city was within a 15-20 minute drive at most. Although we didn't spend much time out there, the patio was another thoughtfully setup space for us to relax or drink a glass of wine.
One note: as others have mentioned, this is a basement unit (though it does have a private entrance). So you'll hear footsteps above you (which wasn't a problem at all for us because we live in apartment with someone above us), but you may want to take that into account.
All in all, we found it was a five star experience and would definitely stay here again if/when we visit Portland again.
Stay at the Hydrangea house, you won't regret it!
