I really struggled to rate this... So call it 2.5 - 3 stars.
I also really struggled with the first part of the book. Almost gave up once or twice. But I am stubborn.
It was a weird reading experience: at times I'd re-read the same sentence/paragraph over and over and still not be able to make any sense of it. At other times the pages would fly by easily and I quite enjoyed it. I do think the lack of context made some difference (context both of common phrases of the time and also the cities). Reading it on my Kindle did help somewhat because I could look up some of the words.
I have read the story before (a children's version) so knew how it ended. I can't decide whether that made a (positive) difference or not. Would I have enjoyed the parts I did enjoy as much if I didn't know where the story was going? I'm not sure.
I have some more (unread) Charles Dickens on my Kindle. Will probably give him another try before I make a decision whether to continue reading his books or not.
