Hello and welcome. I have no first hand experience with this species so my comments will be general in nature.
I live in a flat in Gothenburg Sweden. I can put the bonsai in a balcony where it can see the morning sunlight or in front of a window (indoors) where it will recieve afternoon sunlight.
I would choose the balcony although some protection may be required during the coldest months of winter, see the link below for specific recommendations.
I also have some questions about watering. I have read here and learned about the toothpick test but I just wanted to be sure: I stick a toothpick to the soil and if there is no soil on it I should water the plant?
I don't use this method myself but I did try it out and it works well with a somewhat heavier soil. I suspect it would not be a good indicator if you have a free draining, open soil. After a while you will find that you will no longer need it as you will become accustomed to each of your plants needs.
Anyhow, I used a bamboo skewer, the type used for cooking but any thin dowel or a portion of a chopstick will work as well. The skewer is left in the soil and removed daily to check for moisture. If the wood is damp to the touch there is still moisture in the soil. You can touch the skewer to your cheek or wrist and it is pretty easy to feel if there is moisture present.
How much water and how should I water like using a cup or some other equipment.
Don't try to judge how much
to water, instead always water thoroughly and try to judge when
to water. I use a watering can with a fine head so as not to disturb the soil.
