I have stayed at rich view several times in Tianjin. It is not very sentral, but the subway is only a 1min walk away so its not that big of an issue to me atleast.
The rooms are clean, personell is wonderfull.
They do lack in having english speaking personell, but are quick at getting the personell that do speak decent english if you need help.
If your after a decent price hotel and dont mind having to take the subway to get around this is a great option.
