5 stars for everything. Mark is an outstanding host and more than that, he is just a beautiful person. He will go out of his way to ensure that your trip is fun and one to remember. I was so nervous to travel alone to San Francisco but Mark made it so easy to navigate the city. He gives the BEST recommendations and tips. In addition to this, he gives great life advice and has so many great stories to share with you to make your trip even more memorable. He is also an amazing vegan cook (I think chef level personally) and I have learnt so many new recipes from him as a vegetarian myself. He is clean, friendly, hospitable, fun and just an all round good person. Thank you so much Mark for making this trip one I will remember forever. You have given me a new meaning of San Francisco. I will definitely stay with Mark again and highly recommend his place to stay in San Fran!
