The appartment was nice and clean, a 20min bus drive from the city center. Having a private bathroom was great. Our Chinese host Josh was uncomplicated and correct. One small disadvantage was that the (single) power outlet in the bathroom was not working (tested with two devices, working on other outlets), which is not much of a big deal (electric shaving could wait for 2 days), but should be fixed for future guests.
So far we had a good time in Edinburgh and departed quite satisfied – we would have rated 5 stars / ‚excellent‘ if there was a bit more of a welcoming attitude beyond mere cost-benefit on the hosts end, making the guest comfortable to ask if they need something. E.g. having to ask for every single additional toilet paper roll can leave you with the impression this might already be too much.
