As many of you know, TripAdvisor is a great helpful tool for further travels. People leave their comments there not for commercial purpose but only as an emotional and informative guide to unknown places.
And here is one interesting comment of Odessa Jewish Museum found there:
“An impressive Jewish museum in Odessa.
As others have written, this private, small museum is very difficult to find. (Start with the website at: www.migdal.ru). We asked many people, including tour guides and people at the Main Synagogue, and no one gave us correct directions. Start by asking for Nezhinskaya Street, and go in the direction of 66. Don't hesitate to enter the old building courtyard, and head straight back. The museum is in a flat that orginally housed 3 Jewish families. The museum has collected hundreds of artifacts from Odessa Jews. This is not the usual collection in Jewish museums of torah covers and passove plates, but many photographs, documents and everyday items found in Odessa Jewish homes. There is a small memorial to the 250,000 Odessa area Jews who perished in the Shoah. The person at the front desk speaks fluent English and will give you a full and personal orientation tour and answer all of your questions as you tour the museum. This museum is the founder's labor of love and respect for the Jews of Odessa. It's well worth the effort to find it. Visited July 2013"
