Monica is a great host. She is extremely responsive to messages (of which I felt I had many) and was very clear in her instructions to collect and drop off the key. The flat is a less than 10 mins tram ride into the centre of Zurich and is in a quiet, residential street. The flat is very homely and clean and it made me realise how trusting people are to allow 'strangers' into their home. Lots of nice local bars and restaurant too if you don't want to go in and out of the centre in the evening. I would stay here again.
