We recently spent one night in the Captains Quarters, room 4, to be in the Kemah area for an anniversary. It is far enough away from the boardwalk to be quiet. That was why we chose it above the other properties that he owners have. Even as we were making the booking, they tried to convince us to stay at the Seaside inn...I had no idea why they would do that. When we arrived, I found out why. No one had cleaned most of the other rooms, and no one was there on premise. This would not disturb me usually, however when we entered our room, we found a dirty toilet, carpet, and no cleaning supplies. It appears that they only clean before arrival [vice after checkout] and so 2 other rooms (visible from the porch) were not made up.
The beds were hard, and pilows were cheap $1.99 wal-mart pillows - uncomfortable,
The laundry facility was a washer and dryer that had laundry in it (no other guests were present at the property),
No shampoo was provided (fortunately we brought our own).
All of that said, the view from the porch was great, as is the location - thus the 3 stars). Just plan to provide everything you need, including cleaning supplies, as there is no one on premise for support.
