Couple (31) seeking apartment in Welwyn Garden City

Me and my wife are looking for a new place to rent. We would be so delighted if we get a fully furnished or partially furnished house/flat/apartment though we are open to not furnished ones as long as we like the place. We are looking for a 1 or 2 bedroom house/apartment and our budget for monthly rental costs is around £900 - £1100. Areas we are interested in are areas in Welwyn and or Hatfield. We do not own any pets and we are non smokers
