This was our first time in Paris, so we were all very excited and looking forward to this holiday. We had a day packed with tours planned immediately after our arrival, so we specifically needed an early check-in.All of this had been communicated with the host prior to our arrival to avoid any headaches, delays, or wasted time.We arrived 50 minutes earlier than the standard check-in time and went to collect the keys. Unfortunately, the access code provided to us was incorrect. We had to send several text messages and emails and make multiple phone calls. We were then given three additional codes, but unfortunately, none of them worked.Eventually, the SOS team was able to assist us and provide a correct code that allowed us to access the property. However, by the time the issue was resolved, we had missed our driver and our scheduled plans. What was particularly frustrating was that, despite having communicated our early arrival well in advance, we were not only unable to check in early, but the access issues caused us to check in even later than the normal check-in time.Unfortunately, we experienced a similar issue and miscommunication during check-out as well.Overall, this was extremely disappointing, especially as we had communicated our requirements in advance and had planned our holiday carefully. The unnecessary delays and repeated incorrect information caused significant inconvenience and affected our first day in Paris.
