There is nothing not to love about the Urban Treehouse. The location is great -- if you like to walk, you can get just about anywhere in the downtown area on foot (Balboa Park, Gaslamp District, Convention Center, Coronado Island), and they also provide bikes you can take out for a spin. There are tons of restaurants in the immediate vicinity, too. Nathan's restaurant Craft & Commerce is right across the street, and the rumble from the happy crowds is very present when the windows are open, but we had no trouble sleeping once the windows were closed. Same goes for the frequent train/trolley bells a couple blocks away. We loved listening to music through Nathan's grandmother's big old console radio. The bed is comfortable, the bathroom small but bright, the kitchen corner minimal but perfectly adequate, and the living space and patio to die for. And the view can't be beat! For coffee drinkers, they have a fun Chemex system but no grinder, so if you bring/buy coffee, make sure it's pre-ground. If you're staying for awhile, be aware that some of the fridge space is occupied by mini-bar items (beer, soda) and craft cocktail fixings, so space for your own food is limited. However, we stayed a week and managed just fine. Also, they have wine on tap, first glass complimentary! All in all, a completely delightful place, and Nate and Steph are friendly, responsive, and very helpful.
