We chose this accommodation because we were lead to believe that it was a 15 minutes walk to Wembley Stadium, therefore saving us further travel costs. It was in fact a 45 minute walk (as we found out when we checked the route on Google Maps) or two buses or a taxi costing £20 - one way!
We had no idea where the bus stops were, which direction the buses were going but luckily when we stopped buses the drivers were very helpful! We wasted time trying to find the correct buses and locating any shops and no idea which buses to get, their number or their location.
When we came out of the event we had to wander up and down trying to find which way to get back to our accommodation. Luckily a kind taxi driver who was actually not working agreed to take us!
You specifically told us that it was close to Wembley, for the extra cost of taxis, tubes and trains we could have stayed at the Ibis next to the stadium!
Only two hand towels and two bath towels were provided for three of us!
A number of plug sockets didn't work which was VERY inconvenient.
We were woken by your dog barking around 7ish on the Sunday morning!
When we pulled the sofa bed out there were bits at the 'head end' and the 'bottom sheet' was actually a thin duvet cover with a stain on!
Maybe an info leaflet would be helpful for your next guests?
