My wife, son and I stayed here one night in June 2011 while biking part of the Great Allegheny Passage (GAP) bike route, which runs directly in front of the Trail House. In that end, you can't get much more convenient!
This is a perfectly fine B&B, but with some caveats. If you expect personal attention from the hosts, or even a greeting when you arrive, you'll be out of luck, as it's run with an "absentee landlord" model. But otherwise it served us well for our one-night's stay.
What was good:
When we arrived there was nobody there, which would have been confusing had they not told us this when we made our reservation. The back door was open, and there was a plate of cookies and iced tea in the frig. A note said "welcome, and your name is on the door of your room." We found our room, which was small but fine. There weas a bigger room across the hall that was empty all night, so we weren't sure why they put the three of us in such a small room. They accommodated our son on a Aerobed-type mattress on the floor, which was comfortable and made up when we arrived. The B&B itself is nicely appointed, with plenty of antiquey-sort of collectibles if that's your thing (although we spent most of the time telling our six-year-old son "don't touch that!").
The bed was comfortable, and the house was spotlessly clean. Private bathroom was small but fine. We opted for the full breakfast, which was basic but delicious, with locally sourced foods including scrambled eggs, some of the best sausage I've ever had, local maple syrup and pancakes. They have three pricing models, with no breakfast, continental breakfast, and full breakfast. Unless you have your own food with you, I definitely recommend the full breakfast, as there is no place else nearby to get breakfast. There is a nice back porch with tables and chairs if you want to relax out there. The owners also own the bike shop right next door, which is one of the best-stocked small shops I've ever come across.
Bikes were stored in a locked basement, or in the case of our long bike, in the bike shop next door.
They have a computer for guests to use, and free wi-fi Internet as well, which was a nice touch.
When we did finally meet and talk to the owners, they were very friendly and helpful. More about that in a moment.
What could be improved upon:
As I mentioned above, the B&B is run with an absent-landlord model, as the owners live elsewhere on their farm (not next door or anything). When arriving after a long day of biking, car traveling, or whatever, it would be nice to have somebody there to answer questions, tell you were to store your bike, suggest dining options, etc. Cookies and iced-tea are great, but don't make up for the lack of a human being. Thankfully, I had been to Rockwood before, so was able to tell the other two guests where they could find food in town, etc.
At the very least they should have a "welcome packet" for each guest that explains things, gives dining recommendations, and the like. Because there is little to no cellphone service in Rockwood, it was not possible to call the phone number listed on the door to talk to the owners. We were there for an hour or so without seeing anyone other than the other two guests, then rode over into down for dinner. It wasn't until we came back, around 7:30pm or so, that we saw the owners. But, they were just getting ready to leave after putting the other guest's bikes in the locked basement. Had we not shown up when we did, I guess our bike would have spent the night outside. We also would not have known when breakfast was. So, the biggest take-away here is that communication with guests needs to be improved.
Location-wise, the B&B is across the river from Rockwood proper, and there is no place to eat in the immediate vicinity. I recommend the pizza shop in the Rockwood Opera House. It doesn't look like much, but they make really good pizza and salads.
Freight trains do run through Rockwood all day and night, with the attendant air-horn blowing, but the inn is far enough away where it isn't as bad as it could be. That's just a fact of life in many of the small towns in this area, which were literally built around and for the train line. Nevertheless, I highly recommend taking earplugs along for a sound night's sleep. The inn is also directly across the street from the local VFW post, and we were awakened several times (even with earplugs in) by loud engine revving and people "laying wheels" out of the parking lot (note: to the dude with the beat-up old Ford station wagon in the VFW lot: sorry, man, laying rubber in an old station wagon doesn't make you cool). We were there on a Friday night, so I imagine this wouldn't be as much of an issue on a weeknight.
So, overall, plus marks for the B&B facilities, the bike shop next door, very friendly and accommodating owners (when you finally get to meet them), and convenience to the bike route. "Could improve" marks for lack of communication, no place to eat in the immediate vicinity, and being right on the road. I also think when you are running a B&B sort of place, you should have someone there during the time when people usually check-in, like between 4-6 or something similar, to make sure any problems or questions are taken care of.
