My wife and I had a great stay in this unit.
Location: It's in a great location, maybe a 10 minute walk to the beach, and less than 5-8 minutes to the town. It was our first time in OB--which has a small beach town feel.
The surrounding neighborhood feels relatively safe, although there are no street lights anywhere in the neighborhood. Something to consider if you're out late at one of the numerous breweries or late night taco or burger (Mike's for Tacos and Hodads for burgers). In general it's a great spot if you're looking for a place to be close to the town but not right in the middle of late night noise.
Parking: it is generally very easy to find parking along the street either right in front of the house or one of the adjoining streets, except for Wednesdays, when OB has a farmers market starting at 4:30PM. Good luck finding a spot close by.
Unit: It's definitely a studio feel. It's small but absolutely functional. It's stylish and well-decorated. The pictures are all the description you need, it's all exactly as pictured.
My only "complaints" about the unit is that if there is anyone upstairs, it can be loud. Footsteps and chairs scraping the floor can be heard right above the bed, but it was never happening late at night during quiet hours. We are used to neighbors upstairs so it didn't bother us, but if you go to bed early and aren't used to that, it might be a bother to you.
Brenden also provided some light breakfast (bagels, fruit, muffins) and coffee that was a nice touch!
Overall Brenden was a great host and we would definitely consider staying in this unit or the rest of the house if he begins renting it out in the future!
