I had a great stay at Olivia's. The house was perfectly located (10 mins walking from Dalston Kingsland station), I didn't had the chance to meet Olivia but she was really easy to communicate with and it was really easy for me to pick up the key. Her room was big, clean and quiet for London. I saw two of her flatmates really quickly and they were both really nice to me. I'd totally recommend staying at Olivia's.
