I booked this flat for myself and two sons for over a week, but after our second night we had to leave after a second gas leak and carbon monoxide alarms going off late at night. The first gas leak was the gas company banging on our door at 6 am and the gas being shut off immediately. This left us with no hot water, heat or oven for the day. We were okay and were very patient with the repairs being done later that day. When we arrived home that night the carbon monoxide alarm (that the gas company put in the room where they identified the leak) started going off again. At this point we became nervous for our safety. We contacted the host and had a frustrating conversation over text saying she had fixed the problem and asked if we were causing the alarms to go off from vaping (which me or my children do not do). She seem frustrated with me when I explained there was a strong gas smell in the bedroom and said that was not possible. I told her we would have to leave for safety and she told us to contact Airbnb. At this point I would assume that a host would be doing all they could to help out and find emergency accommodation, or recommend a hotel but we were not helped at all. We packed our bags and stood on the sidewalk with two kids at midnight in the cold in a foreign country with no place to go. I don't want this to seem like a rant. I have had rough experiences at a few Airbnb's but I have always received help from hosts to make the situation better. This is my first negative review and I wish it had been perfect and not been so disruptive to our vacation.
