Frank's place was great for a short visit to Toronto for me and my teen daughter. The space is small but efficient and well organized and we're both on the short side, so the low ceiling was not an issue. The location is great -- so many restaurants within a few blocks and a subway entrance right around the corner.
Two things to note are 1. that it's a tiny bit tricky finding your way in the first time and I was glad it was daylight out and 2. you do get a little rumbling from the subway going by between 6am-midnight but it didn't bother us.
