15 min taxi ride to airport great location for airport transit, but to get to london 15 mins walk to tube and 1 hour ride or 15 stops just to get to piccadily circus area so depends on your reason staying

Much much cheaper than staying in central london. Downside is the 30-40 mins travel of always crowded Picadilly line train. Hate the size of the toilet and bathroom. Otherwise still acceptable sleeping space. The breakfast, it could be better if egg and sausage are served. Travel tips, can get to Windsor castle using the sw railway from Hounslow train station. Don't use Oyster card on railway as some station it is not accepted.
