I spent a week in Tel Aviv in February 2017. It was my first visit of Israel and I enjoyed my stay in Tel Aviv a lot! I must say: I would not have a temptation to leave the city and go to a tourist trap of Jerusalem even after one week at one place.
My impression was that Tel Aviv is a blend of Berlin with a mediterranean spirit.
That is true that the condition of some houses is poor (however, it has been improved a lot) and their appearance have been changed, but what I found unique in Tel Aviv is that there is a huge ensamble of such houses. In Czechia, we have only limited number of buildings in the international style and only few billionars would afford to have a house in Bauhaus style...
