The search is linked to Google Places, some places are not listed there. You will mainly find restaurants, cafés, parks, museums, zoos etc. If necessary, expand your radius and/or try out a few spellings if you are looking for a specific meeting place. Alternatively, you can simply enter a street (with house number, if applicable) or just the city and refer to the exact meeting place in the description.
In case of need, simply choose a location nearby and indicate the exact meeting point in the description.
