There is a wide range of hotels of all categories and price ranges.
A few decent, resonably priced, and well located places are
Hotel Admiral, Karl Schweighofer-Gasse 7, 1070 Wien
(website).
Carlton Opera Hotel, Schikanedergasse 4, 1040 Wien
(website).
Hotel Terminus, Fillgradergasse 4, 1060 Wien

We recommend planning your trip well in advance. Though summer is not the most a popular and busy tourist period,
hotels can be fully booked quite some time in advance.
