Central Glasgow never really goes to sleep, so downtown hotels will be noisier than those in the leafy and genteel West End, convenient for museums and art galleries, or southern suburbs, convenient for the Burrell Collection. The flip side is that most downtown hotels are within walking distance of all the main sights, whereas you will need to make use of the (excellent) bus service if you stay in the suburbs. For country-house luxury beyond the city, you might try Mar Hall, near Paisley.
