Dotti's house is in a terrific location in a very lively and interesting section of Amsterdam. Outdoor cafes, shops and the large daily outdoor market are just a couple of blocks away. Everything is within walking distance and, if you prefer public transport, tram stops are less than a block away.
Dotti was very welcoming and provided a map and a wonderfully detailed and professional guidebook that she and a friend had written. Following her suggested routes was the perfect way to explore Amsterdam. She was also very helpful with museum tickets and advice for city visitors.
For me it was the perfect combination of being able to explore on my own and return to friendly faces and interesting conversation at the end of the day.
