I would certainly recommend staying at Leletta's place. The apartment is very comfortable - it has a large terrace with a view over Athens rooftops, spacious and light rooms, a well-equipped kitchen, and space to work if needed. It was very clean and well-maintained. The hosts were friendly, hospitable and accommodating. We were able to walk to the centre and many of the sights, and there are plenty of cafes, bars, restaurants and shops in the vicinity.
