There's a nice set of books by Frances and Joseph Gies that accessibly describe life in medieval cities, villages, and castles. They're good if you want an overview that isn't too long. They were also published together as a single book.

I do not know enough about common medieval life to tell you about it myself. But I would highly suggest you read this book.

It is fairly short (138) pages, but it is a great insight to one peasant woman's life in early 14th century England. It goes into pretty good detail on the life of a peasant and what things would be like on a daily basis. I enjoyed it.

I have no idea about the accuracy of the plot, but Frantisek Vlacil went to great lengths to ensure that all the props in his film Marketa Lazarova were accurate to the 13th century:

"Every detail, starting with nails, had to be made for the film. I had most of the props- tools, weapons, etc- made not with modern equipment but the way they were probably manufactured in their times."

Vlacil also did a good amount of research into the time period, but in his own words, felt "the period in which Marketa Lazarova takes place is pretty much a historical blank. There is very little reliable information concerning the mentality and life of the people of the twelfth century [sic]. Historical advisers told us when we were through that we had succeeded in expressing the times very accurately, without being able to document them in any way" (From Antonin Liehm's "Closely Watched Films: the Czechoslovak Experience", reprinted in the booklet included with the Criterion Collection Blu-ray/DVD)

The film recently received an absolutely gorgeous release from the Criterion Collection, and is one of my favorites even though it is dense and requires quite a few viewings to comprehend.
