My home has vaulted ceilings as well as tile floor throughout the entire home minus the hallways and the private room that is listed. So yes it may slightly echo with 35 foot ceilings if you are going to be planning on being loud.
Also llama, it is only a 12 minute drive from the strip. No matter where you stay off the strip it is a typical 20-30 minute drive.I have lived all over vegas, So a 12 minute drive to any down town area is quite fast. In regards to the room, paying 75 dollars to have an entire upstairs living quater entirely to yourself is quite inexpensive especially for the type neighbor hood I live in, along with the amenities I provide.
I am sorry you also feel that you could not "Get intimate" It is very clear in the listing that is a space with to extra large twin beds, it was your choice to book, the listing is very clear and accurate.
No other guest has ever had issues with my home and have kindly and have e ALWAYS given me sincere gratittude . Maybe booking a hotel suite on the strip and paying 3x as much would be a better option for all your needs next time.
