The airport in Shenzhen is Bao-an and it's quite a distance to
the city. You need to get to Luohu in order to take MTR to
Hong Kong and that's the Chn-HK border. To get to Luohu, you
can either board a airport bus, take a taxi or ask the taxi to get
you to the nearest subway Jiu-Guang station and from there find
your way to Luohu, you might need to change train direction once,
like City Hall or Raffles Place MRT. That is very troublesome
and time consuming. Once you get out from Luohu station, you
go through the Luohu commercial centre and find your way to the
immigration checkpoint and from HK side, hop on a MTR to your
destination.
The easiest way is like i said, take a bus that goes direct to
Hong Kong and even the immigration check is faster. Get the
one that goes to Mongkok at Kowloon, there you will find budget
hotel at good location.
I stayed in seaview many times. The exact hotel for the
hotel is "Dorsett Seaview Hotel" at Yau Ma Tei. The
rooms are very small, like most cheaper hotels in Hong Kong but all
facilities are there. The thing that attracts me to stay in
seaview is the location. It is at the heart of Temple
street. Go behind the hotel you get lots of food at temple
street and further down is Mongkok. On the opposite side you find
all the fortune tellers and sex toys vendors, it leads you to
Jordan and you can walk the night market all the way to Tsim Sha
Tsui. Of course where are many nicer YMCA hotels in Mongkok,
but again, it the location.
Also the MTR is 50 meters away from the hotel the station is Yau
Ma Tei. Lots of good food everywhere in Temple Street and
Mongkok. Must try the Yunan Guo Qiao Mian Xian 云南过桥棉线, and
the Che Zai Mee 车仔面at Woman's Street in Mongkok. Be prepared
to share table with strangers if there are still empty seats.
Wherever you stay, don't stay in Hong Kong island hotel, they
are expensive and nothing exciting there except the Lam Gui Fong,
Pacific Place, IFC tower, that's all. All the actions are in
Kowloon.
Book your hotel before you go. Find your hotel here :

website, no online credit card transaction, you pay at the
hotel.
For Shenzhen, just be extra careful especially ladies.
There are many pickpockets and conmen. Just hang on to your
valuables tight in crowded place and don't entertain strangers who
offer you things on the street.
If you plan to visit Shenzhen also, I will offer you separate
advise.
