We had a really great stay at Katie's apartment. The flat is spacious and well equipped. The kitchen is especially well equipped and had everything that we needed to cook with, and there was even tea, coffee, oil etc. in the cupboards so we didn't have to buy those essential bits for our short stay. The bedrooms are all a good size and the beds and bedding were really comfortable.
We arrived by train into Waverley and it was easy to get the apartment with our luggage using the number 29 bus from Princes St. We really liked the Stockbridge area and there are many lovely shops, delis, cafes just around the corner from the flat. As we had a toddler with us we tended to get buses around the city (timely and not too expensive). The walk into the centre is uphill, however, returning downhill was easy enough for us all to do on foot and took around 15 - 20 minutes. I would definitely recommend staying in this location - it has a friendly neighbourhood feel without many tourists but is very close to the main attractions of the city.
