I highly recommend Andreas place. You are literally across the street from the coliseum! There are plenty of bus stops around the corner, restaurants, bars, and markets. Suuuuper convenient. I think its a great location for exploring. From Andreas, you can walk to one of the main city centers that has great shopping and amazing sights.
His place is terrific, the lining were fresh pressed, the space is a great size with a dining table and pull out sofa bed in the living room, which was easy to set up and tuck away in the morning. Great views and great energy in the space. Checking in and out was easy and convenient.
