It's one of the most visited tourist attractions in the world but to some visitors, Buckingham Palace is seen as "smelly" and "uninviting," according to reviews posted on TripAdvisor.
And, even the Queen herself isn't safe from the one-star ratings with one visitor scalding her majesty for "not letting them in when it was raining".
Most of the nearly 30,000 reviews of the palace give it five stars.
The majority of negative complaints seem to come from people unfamiliar with the historic protocols of the royal family and the palace.
A visitor from Connecticut was under the impression the palace guards were only there for entertainment.
"My friends and I were playing around with those street artists who are supposed to stay completely still. I kept poking the guy to see if we could get him to move. Then I tried to take his hat off and put it on. It was just such a silly and fun looking had, I had to try it on. But I was not expecting to get a fist to the face! This man is not professional and he should be FIRED," he said.
Some of the more interesting reviews on TripAdvisor:
"They wouldn't let us in. Even though it was cold and rainy outside. The guards couldn't even smile for a second. The queen refused to open the door or even wave at the window."
- "A very busy former roundabout."
- "£24.99 for an hour walking round seeing nothing but large rooms."
- "I went to Buckingham Palace to deliver some SDMN beanies but she never came out. I was upset. hope people learn from my mistakes."
- "A soulless cold and unwelcoming smelly old building lacking in history."
One parent labelled the guards as "aggressive and intimidating" after they told their child not to climb on the fence.
"My 5-year-old son was messing about on the fence. But that gives one of the guards no right to shout at him to the point of where he p****s himself," she wrote.
"Absolutely shocked about the guard's reaction to an innocent little boy playing about.
There were some visitors who seemed to be under the impression a visit to the palace would be similar to a trip to Madame Tussauds, than to a working palace.
"The Queen refused to open the door or even wave at the window."
Another person agreed, saying: "The Buckingham Palace tour is probably the least welcoming tour I've been on in the British Isles. Not only are there a lot of strict rules, but the guides are about as condescending as people can be paid to be," a disgruntled visitor wrote.
And one reviewer didn't quite seem to understand the concept of daylight when asking for something to be done about the lighting.
"I would like to request better lighting in the evening. It was very hard to see the palace and take a good picture."
