This was probably the most unique experience I've had on airbnb. First off the place is massive (I sorta wished I wasn't staying there alone) but then, its not difficult to make friends in Riga. Central to old town, you're within walking distance to basically everything touristy. Calling a cab can be tricky since they can't enter old town, but you can meet one further up the street. Check in and out was a breeze, though finding the spot was slightly more tricky than usual since it's under ground. There is however, a big sign that has the name of the place above the entrance/staircase. Recommended!
