You've never been to Sochi in the summer. Imagine 29 palms with high humidity. Russia's other hell.
Actually it isn't that hard to get around Moscow. If in doubt some policeman will come around and start speaking in a very neutral American accent if you are lost. lol Glad he showed up, as it;s a long walk around the Kremlin and they do't exactly advertise restrooms, or Toilets as they are called there.
Two others that are difficult, restaurant and otel. Remember p'sa re r's and l's look kind of like n's. restaurant is pestaupant and a hotel looks like oten. Saw the Notel Otel in Sochi. Don't think they meant that, but it was a classy joint for taking the mistress out.
