Esther is a charming, interesting guide. She took us to a great wine bar and then to a family run restaurant that's been around since 1931 where we sampled many excellent Roman dishes. We could have gone for gelato afterwards, but were too full to do so. If you are looking to experience a bit of Rome outside the touristy areas I highly recommend this tour.
What a great hike! I've been to San Francisco more times than I can count and Alex took us places I didn't even know existed. A couple of highlights: being suddenly engulfed in fog on Twin Peaks and hiking through a eucalyptus forest in the dark—the sound of the wind in the trees was incredible.
