Hi @zkalemiss, thanks for the question. Sometimes I try not to give so much information afraid to be boring.
Paris was a mixed emotion city, the building and churches were amazing, but the people there are not very friendly, if you don't speak french they are not very welcoming.
I'll make another post with the churches and maybe about Opera Garnier, for me one of the best buildings in Europe.
Regarding the prices, Paris was very very expensive, in comparison with Italy or Spain.
Cheers!
