Angleterre is well located in central Grenoble. The staff are very helpful with things like driving and parking directions. This is my second time staying there. This time I got a very nice large room (by European standards), and since it was not facing the park, it was very quiet.
I definitely recommend the hotel if a reasonable price is available.. The price I got through Skoosh was pretty reasonable, but I think the regular price may be too high for the quality of the room. My only criticism is that the breakfast is overpriced, particularly given the present exchange rate. On the other hand, you can drink as much coffee as you wish!
One small feature which I haven't found in many small European hotels is that they have a supply of newspapers, including the English language Herald Tribune. Its a small thing, but a definite positive.
