I was always struggling to find a comfort zone there. Noisy, dirty, crazy traffic, awful buildings at suburb. I didn't find any beautiful architecture at city centre, I dislike how they decorate their apartments inside. And general attitude of the majority of local looks like this: you are white, this mean you are Russian and this mean you are rich. Give me you money! They try to charge you as much as possible. Regarding mountains, you can find first beautiful landscapes at Mtskheta something about 20 kilometres from Tbilisi. Landscape at Tbilisi itself resembles some Martian scene.
