Contract Renewal

I have to renew my apartment contract next March.
I really like this place and it has passed 5 five* years have passed {or "gone by"} already.
It was the first place where I wanted to live in Tokyo.
I decided to live at here within 3 three minutes from when I came here for the first time {better: "from the first moment I walked in} I guess.
Actually, the interior design is very nice and I couldn't find another such as nice ever.
The ceiling is very high and there are the owner who is an interior designer made designed the lighting, and also the colorful tiles that　are laid installed on the porch, kitchen and bathroom.
But here, it is quite small and that is the one problem.
So I started to thinking to about looking for another apartment, but it may needs more money and times** and that is my worry now.

*Numbers up to ten are spelled out.

**It reads slghtly better as "...it may cost more money and take more time...
