Nice place well located w a few issues

Nice enough place well located steps to downtown. Room was clean and nice w comfy bed. Room lacked bureau for clothing storage. Bathroom and shower nice but you may want to do something about slippery shower floor. My big grip is the mandatory $45/night valet parking.
