My husband and I booked the Post House Inn for our first anniversary. We found that it was less expensive if booked online than over the phone, so you might want to consider that when booking. Our 8 pm (after hours) check in was a bit awkward (done with lockboxes) but the instructions made sense once we were in front of the door.
The location was great - we walked to a packed Irish Pub for dinner on Friday night and were right on the main street for wandering around town on Saturday.
We found the room cold (it was the end of October) and had a tough time regulating the temperature, but the electric fireplace helped. The room itself was nice enough but the bed provided zero back support. My back was so sore in the middle of the night that I spent half the night sleeping on the floor (don't forget it was our anniversary!)
We showed up for breakfast at the recommended time. The food was good and plentiful and we had a great conversation with the other guests.
When I asked Barbara if we could move to a different room with a better mattress, she said that although there were no available rooms at the Post House, she could move us to another B&B that she owns just down the street. So although it was frustrating that we had to pack and move, at least I didn't have to spend the rest of our anniversary on the floor!
(Of note, the other B&B is called the Burke House - it was equally lovely).

Stayed overnight recently. Hotel itself is ok, but we had major dramas about which we are still furious. We checked out on the Saturday morning and upon arriving back home, realised that one member from our party had left some clothing behind. We immediately contacted the owner to ask her to gather the items and we would pay to have them posted back to us. In her response, she said that she would be charging a $25 "admin fee", plus postage. This was upsetting to us but we felt we had little choice if we wanted the clothes back and so we said she could use the credit card she had on file. We then waited for the parcel to come in the mail.

Imagine our shock when a COURIER arrived at our door with the parcel! The innkeeper had no permission to misuse the credit card in this way and in the end it cost almost $70 to get the items back! When contacted as to why she had used a courier without permission or discussion, she just said we should say thank you and offered no explanation!

We are baffled and extremely upset and we will NEVER set foot in there again.

Firstly, the check-in times are weird and too strict. For the money, we had high expectations of the room, but were very disappointed. There were appliances in the room, but there was a note to say that nothing could be used due to some local bylaw. Not sure why they aren't removed altogether as it looks silly. If you have a third person with you, expect to pay a huge surcharge for them sleeping on a rather poor quality fold out couch. I don't think I've ever paid more than $20 for an extra person in a hotel room, but here you have to pay about $60.
Wallpaper peeling in the bathroom looked poor. There is a thermostat and a gas fireplace which were almost impossible to regulate together.
Also, there are fake plants everywhere which is very unappealing.
Breakfast is ok, but don't expect anything hot if you come close to the end of the breakfast time, you'll just have to make do with whatever is left on the table, even if it's cold eggs and pancakes.
Overall, would never stay here again - we've travelled all over the world and have stayed in beautiful places which cost less than this inn. Only positive thing about the inn is the location to the main street.

This was our second visit to Niagara-on-the-Lake, and we have stayed at the Post House Inn on both occasions The rooms and facilities are very clean and well maintained and seem to retain their new look. The breakfasts are good, but not so over the top that you don't want to eat for the rest of the day. Barbara is very good at making everyone feel comfortable at breakfast and getting to know your fellow travelers. She is also very good with suggestions on what to see and where to eat dinner. We would definitely stay here again!
