public interface PostReviewApi {

Answer 1

Try using @Body annotation instead of @Field and passing a single ReviewBody object.

class ReviewBody {

    public Review review;

    public ReviewBody(int placeId, float rating, String content, List tagList) {
        review = new Review(placeId, rating, content, tagList);
    }

    public class Review {
        @SerializedName("place_id")
        public int placeId;
        public float rating; 
        public String content;
        @SerializedName("tag_list")
        public List tagList;

        public Review(int placeId, float rating, String content, List tagList) {
            this.placeId = placeId;
            this.rating = rating;
            this.content = content;
            this.tagList = tagList;
        }
    }
}

@POST("/")
void addReview(@Body ReviewBody body, Callback callback);

(without @FormUrlEncoded)
