My mom, my daughter and I spent a year at Leo&Veronika's place. I would highly recommend the apartment to anyone, especially for extended stays. The place has all the possible amenities, which makes daily chores easy. I mean, there was even a blender. And all the pans and plates you may need. I liked the home-like feeling about the place - the carpets, the armchairs etc. Bright overhead light with extra standing and bedside lamps. Some of the lights are even dimmable. We liked to keep the balcony door in the living room open most of the time - it overlooks the garden with a lemon tree, sometimes we spotted hummingbirds there, and once even a flock of parrots.
Leo&Veronika are very accommodating and quick to respond. They even made a small change to the furniture arrangement which I highly appreciate.
The location is very good. The only disadvantage is the steep hill you have to climb every time you walk home. But that hill also allows you to be very close to nightlife without all the noise. And it is a perfect spot to watch the New Year fireworks. The place is exactly between Chinatown, Little Italy and North Beach - lots of cafes, restaurants and nice shops. Do stop at Cole Hardware for absolutely anything you may need at home, including souvenirs and toys. Cafe Trieste next door opens at 6:30 every day (very helpful sometimes), do come there in the morning at least once to check the atmosphere and watch the public.
Exploratorium and Pier 39 are a nice 15-20 minutes walk away. There are a lot more treasures to discover in the vicinity.
All in all, it was a splendid stay. Best memories.
