The historic centre of Oxford is as notable for its beautiful period buildings as it is for its beautiful university colleges. Tourists and scholars alike flock to the citys prestigious colleges, commonly set against a backdrop of charming, well manicured grounds. The river Cherwell and the Oxford Canal meander through the city, meeting the Thames south of the centre. Accommodation in the city centre, and fashionable Jericho district, is extremely sought after, and subsequently comparatively expensive. Here there are mainly apartments in keeping with the surrounding architecture, rather than private houses. Residents in this area tend to be professionals and academics who have recently relocated to the city on a short-term basis. Consequently, the turnover for letting is high. The city centre also encompasses Oxfords main shopping streets, where there are a maze of high-street stores and lively boutiques, bustling cafes and restaurants, and lively pubs and bars to suit all tastes. The streets throng with people day and night, and traffic in the centre is kept to a minimum, thanks to the popularity and accessibility of the park and ride bus service, which operates from five points on the outskirts of the city. The coach and railway stations are also conveniently located, servicing destinations across the country.
