Collin's place is in a wonderful, central location without being located directly among the madness that is Market St. There are several great bars, restaurants, and activities in the area that cover a gamut of interests and budgets. Speaking of budget, Collin's place is priced very reasonably for the area and will absolutely be high on my list the next time I'm in SF.
Collin was an excellent host despite being incapacitated during my stay. He responded quickly, clearly, and with great wit! I hope next time I'm actually able to meet him in person as I imagine that would have made my stay even more enjoyable.
