Markup Review

Advertises holiday accomodation in Wisła, Poland.

Fairly clean usage of HTML5 structural elements. Nice use of new form input types email and tel in the contact form. The intro section is empty on most pages, only containing a header, which seems a bit redundant. Also bear in mind that more than one h1 element can be used on a page. Remember that the type attribute is not required on script and stylesheet link elements.
