    const headers = new Headers({'Content-Type': 'application/json'});
    return this.http.post('http://localhost:8000/saveFacility', 
facility, headers)
    .subscribe(
    (response: Response) => {
    return response.json();
},

RxJS library provides Observable operators which you can use to manipulate the data being emitted like map, filter.

Try using map operator:

    saveFacility(facility) { 
        const headers = new Headers({'Content-Type': 'application/json'});
        return this.http.post('http://localhost:8000/saveFacility', facility, headers)
            .map(response => response.json())
            .subscribe((response: Response) => {
                    return response.json();
                },
                (error) => {
                    return error.json();
                }
            );
    }
