Had the opportunity to visit Iran for 2 weeks just before the COVID 19 outbreak. As much as we hear a lot of stories about this country in the media, Iranian is one of the friendliest people I met in my traveling.
Lots of history, culture, and architecture.
This is the first hotel we stayed when we arrived. It was converted into a hotel from a traditional house. Rich people in Iran built their mansion by digging down, not building up. Our tour guide explained that in the old days, when bandits attacked the city, they could easily tell where the rich people lived if their houses were visually big.
However, if they dig down, all houses big or small would look like the same from the outside and thus avoid being an easy target.
