Very difficult to contact hosts. Offered early check in which we were grateful for. Arrived at discussed time no one was there then could not reach host by numbers provided. Finally reached someone and they said to come back at 3. When I initially made the booking I waited days for a response. When they did respond I was told they were very busy and had a lot of people to get back to. Then don't say on your site 1 hour response. When we were checking out we were walking from top floor to bottom to leave and the host was coming up the stairs. I think this was at 11:03 so within reasonable timeframe of leaving. I've stayed at a lot of Airbnb's in many countries and never had a host walk in on us. I was an Airbnb host so I totally understand turnaround times but also understand if you forgot something or need to check to make sure you have everything. Giving people 5 or 10 minutes when you can clearly see they're leaving is acceptable in my eyes but perhaps not for other hosts. We then went and stayed at another Airbnb in Porto where they followed through on everything offered.
