If you find yourself visiting Ipswich you should, first, reflect on the life choices that brought you here and, second, book a room at Pentahotel Ipswich.
Pentahotel Ipswich is wonderfully located within walking distance of the Ipswich train station. The rooms are clean, modern, well-maintained, and generously sized. This is a well-managed, excellent, two star property that is (in terms of relative quality and style) a cross between an Ace Hotel and a Holiday Inn.
A few very minor criticisms follow. The free wifi is rather slow (there is a higher-speed, paid option available). Check-in is, oddly, located at the hotel bar so you may need to wait for the staff to finish mixing a whiskey and soda before they can give you your room key. Corridors are slightly dreary. The retro telephones inside the guest rooms, while very hip, are essentially impossible to use.
UPDATE - I stayed there a second time in January 2017 and nothing has changed, it's still a great value, well-kept, and centrally located. Really, the only downside is that it's in Ipswich.
