I’ll go to Kyoto on a sightseeing on trip this summer vacations.

And I have not a command of English anywhere. (this doesn't make sense)

So I will go to Kyoto and stay the in a Hhostel, it stays hosts several foreigners.

And then, I’ll talk with them, and I will also guide to them around Kyoto.

I want to talk with them so much talk with them and I will also improve my English skills.

So I am thinking about where I am going.

First of all, I have a little time for 1st day so I’ll go to 1 or 2 sightseeing attractions.

2stnd day, I’ll walk so much walk on the streets and go to temples or shrines while I am talking with them as soon as I can.

I will do my best for while talking with foreigners.

I’ll go sightseeing in Kyoto this summer vacation.

I’ll go sightseeing in Kyoto this summer vacation.

Because I want to brush up on my English skills, starting from the basics.

And I have not a command of English anywhere. (I'm not sure about what you're saying here. Perhaps that there is no place where you can practice English?)

So I will go to Kyoto and stay at the hostel; several foreigners stay there.

And then, I’ll talk to them, and I will also guide them around Kyoto. (But this is a little awkward. Maybe it can be "I will also be a guide to them as they go around Kyoto.")

I want to talk to them a lot and improve my English skills.

I’ll stay in Kyoto for 3 days.

So I am thinking about where I will be going.

First of all, I have little time on the 1st day so I’ll go to 1 or 2 sightseeing attractions.

2nd day, I’ll walk along streets a lot and go to temples or shrines, while talking to them as much as possible.

I hope to talk to them and improve my English skills.

I will do my best to talk to foreigners.
