I would recommend you look at the
Wroclaw Hotels page. After reading it over i would say that the The Radisson SAS hotel sounds idea for you. It is situated away from the city centre in a quiter location. There you have views of the Odra River and you are also surrounded by a beautiful park. This sounds ideal for a break where you are looking to take a rest.
For ideas on places to visit on your trip you could look at the
things to do section. You could enjoy some Arts and crafting in the Old Town, Cruise along the Odra. visit the Szczytnicki Park, relax at The Rynek Square. and much more. I hope this helps
