Mika's place was a good value for the money. It was very clean, well air conditioned and centrally located to the "hot spots" hat Athens has to offer. She was very helpful and accommodating as me and my girlfriend had an unusual check in time. Made our experience much less stressful. THe place is close to the metro station which is super convenient. Airport is about an hour by train, don't recommend a taxi as it can be very expensive.
Two downsides-- lots of stray cats in the neighborhood and bathtub is much smaller than in pictures.
Overall, the place was nice and clean, would definitely recommend.
