To access the Birdhouse, you must first find on-street parking then walk to the back alley and locate the correct yard to enter. This seems simple enough except when you arrive after dark, can't find on-street parking, are wearing high heels and carrying luggage. Having a sign advertising the Birdhouse on the appropriate yard would be tremendously helpful.
On the plus side, it is very close to downtown and the neighborhood was quiet. Although it was located in a backyard, it still felt private.
