I was very disappointed with Helen. Made my reservation and a few days prior to my arrival, I contacted Helen to let her know the time of arrival. Helen contacted me with her cell phone asking me the time of arrival. I replied but didn't get any confirmation. A couple days prior to my arrival, I messaged Helen again (Airbnb and text message) to remind her of my arrival time. Never got an answer from Helen. Arrived at the home 20 min later than expected (due to public transportation delays), rang the door bell and nothing. Went to the nearby hotel to find a public phone to call her, and it went straight to voicemail. I left her a voice message. I was left with all my bags while exploring London. Later that afternoon, I tried to call her again, but without luck. It went straight to voicemail once again. I messaged her on Airbnb and sent a text message saying I had arrived in London and had rang her door bell. Helen ended up to never get back to me. Long story short, I was stuck with all my luggage while exploring London. Later that day, I was considering sleeping at the train station due to my budget. Stayed at a cheap hotel last minute. Helen FINALLY contacted me TWO days later saying that she thought she had told me she had left the house key at the nearby store for me to pick up. I never received that message! I find so irresponsible that a host makes herself unavailable knowing that she has guests to accommodate. I can't understand why it took Helen 2 days to contact me after the day of my stay, after I contacted her on Airbnb, text message and even trying to call her personal phone. I wish I could have left a more positive feedback, but this brought such a great stress to my vacation.
