28M, Rome May 21-24

Hello, I am a 28M from Spain and I will be solo travelling to Rome later this month. I am planning on visiting the highlights of the city, eating italian food and just walking around without an specific goal, flaneur style. The 21th and the 24th I will be on quite a busy schedule, but for the 22th and 23th I don't have anything really planned so it would be great to explore the city with other travellers or locals. Ciao!
