Good: The location was fantastic. You are right off 14th Street where all the trendy restaurants and shopping are. Trader Joe's, CVS, etc. were all in very convenient walking distances. Communication was great as the hosts quickly answered any questions we had. The kitchen was probably the best stocked one we've seen out of all the Airbnb's we've stayed at.
Bad: The bed was incredibly uncomfortable as the mattress sinks in the middle. Had very bad back pains during the stay. Because the Airbnb is a basement floor (there are units above it), getting in and out of the apartment for two people was awkward. You have to duck under a staircase, unlock a gate and then the door in a very tight space. And the upstairs noise (esp. because of a dog) was very noticeable throughout the day and night.
