Yes, it is a dated property, yet the rate paid was a direct correlation to it. If you want newer and modern, pay accordingly.
However, with no sunset in the summer, some sort of blind is definitely needed. Also, figure out how to keep the solid doors from slamming! Awful in the early morning and evening worse in the late nights trying to sleep. Warn guest there is a loud/late events happening during their stay. Put them away from the noise, not right above it. Between the power boats revving their motors between 11pm-2am and the bands going until the week hours, doors slamming all day long and no blinds….my 4 night stay, was miserable. I took naps in the park twice as 1-2 hours of sleep was all I could get.
