This host changed the location of our stay less than 24 hours before our trip. We were already en route traveling with our 1 and 3 year old children and were unable to find alternate accommodations. The apartment they placed us in had one less bedroom than the place we booked and had a loft that is dangerous/not suitable for kids. The building did not have an elevator like the listing we'd reserved and appeared older than the listing we'd booked. We asked to be moved when we realized the apartment was not suitable for kids and they were unable to accommodate us.
With that said, the host was very communicative and responsive, and friendly. They did not explain the circumstances surrounding the switch of accommodations but it was quite an unexpected inconvenience. We had an issue with our key while we were there and the host fixed it very quickly and was kind and helpful. I did want to be sure to communicate that they were very nice despite the unfortunate switch of apartments.
