What Do I Think of Taipei?
I like to live living in Taipei because of these reasons. You can also say: "for the following reasons:" as it sounds more natural.
First of all, Taipei is a modern city with a beautiful scenery.
Secondly, Taipei has a very convenient public transportation system and a high-speed railway.
Most important of all, this city offers people many entertainment activities.
Therefore, I think that this city is comfortable and convenient for people and interesting to live in.
There is nothing grammatically wrong with "this city makes people feel convenient", but "convenient" is not used as a feeling.
I also changed the last sentence a bit to make it flow better.
