Martina's appartment is located on the popular and lively Langstrasse street in the centre of Zurich. Numerous bars, restaurants and grocery stores are in walking distance to the appartment. Zurich main station is very close too.
Martina was a friendly host who can give her guests lots of recommendations on where to eat, shop and party in the city (if you're interested). I particularly liked the cleanliness of the shared rooms (bathroom & kitchen) and that despite being on a major street, it was not that noisy (the room I lived in is not facing the main street).
