I had had a very pleasant 5 day break at Felix Rodriguez's apartment. The room was coforatable with a desk. The wifi was very good, and there was coffee available that was very nice indeed! The bathroom and kitechen was shared, but always immaculately clean.
The location was new to me even though I had stayed in Zurich before. A few hills, but walkable to Altstetten, and well served with public transport.

I would not hesitate to stay again!
