My friend and I had a wonderful stay in Pietro's apartment. The apartment is well located, close to public transport links and supermarkets, and if you like swimming outdoors you are in for a treat in the summer months as it is a very short walk to Unterer and Oberer Letten.
The apartment was really clean and tidy when we arrived and had everything we needed for our short stay.
It is located on the top floor of the block (there is no lift so be wary if you have mobility problems or heavy bags) but this means that there is a beautiful view down to Lake Zurich, Uetliberg and the mountains beyond.
Pietro was very friendly communicative, responding quickly to queries. All in all, we would highly recommend a stay here!
