#3 Could I ask for validation of my composition?

In advance, thank you for your advice, Mr.grammarfreak and Mr.Clive.

I have once again slightly modified the second version of this letter but I am not yet certain that the sentences is correct and logical.
The phrases in bold are a causal clause; please validate my composition, especially the phrases in bold.

I was very glad to have received your email that I had not anticipated because you are easygoing person,
but It's true that I was very happy when I heard from you.

As we had a few hot days here in Korea this summer and even though rainy season is between mid-Jun and late July originally, we had a little rain in this season, I had more comfortable summer days this year than any other year.

I didn't travel this summer for several reasons and It is unlikely that I will travel for a while, but I will fully take a trip to Canada some day even though I don't know when yet.

I am looking forward to seeing you sometime in the future, taking coffee with you, chatting over a nice meal and watching your home with a wide and gorgeous garden.

p.s. If I will be there, could you show me your beautiful house?
