Definitely 5 stars from me!
Upon inquiry until the last day of my trip, Sam has been responding quickly to all my messages. I never encountered a problem with him or his friend Elise (who took charge while he was out on holiday) in terms of communication.
As for the location of the place, it was very convenient to find since it is located in a very good neighborhood. Plenty of restaurants to choose from on Victoria, Surrey and Darlinghurst streets! My favorites were Buffalo Dining Club, Gelato Messina and Bar Coluzzi, which are all 2-5 minute walk from the apartment. A small grocery (I forgot the name), Chemist store and Coles are nearby. Kings cross station is approximately a 4-5 minute walk. A busy street also means it's easy to flag down a taxi passing by or booking an uber.
The apartment itself is very spacious for 3 people and our large luggages. Everything we needed was there, very clean and well-stocked as well. It truly is our home away from home. When we arrived from the airport to drop off our things, I met Elise. She even brought fresh Australian flowers for us! We came during winter so we expected to use the heater a lot. True to what Sam told me before, the apartment stays warm even without the heater on. My only comment about the place is that the bathroom faucet can be quite challenging. There are 2 separate faucets for hot and cold water, set opposite each other, making it hard for me to wash my hands with the perfect temperature. Easily remedied by using a cup getting half hot and half cold water so it's not really a big issue!
Over all, my stay was very pleasant and I would definitely book Sam's apartment the next time I visit Sydney. The moment you see this apartment available on your travel dates, book this place immediately!!!
