I am not sure we would have found it but - miraculously - the people sitting next to us on the tram were on their way to the church and we had only to go with them! God is so nice, sometimes. The actual chapel was upstairs, and quite difficult to find. The service was quite long as there was a baptism, and a farewell to a diplomatic family who were moving on, and a presentation to a couple of people who had been confirmed in Vienna last weekend.
After the inevitable coffee (surprisingly drinkable), it was time to go, and we went on a direct metro line to Keleti station. This time, our first train was 20 minutes late, but that didn't affect our connection to Hortobágy, which was hot, slow, second-class only and on time! It was a beautiful journey across the Hungarian plains, some cultivation but not much, and scattered farms or ranches reminding me of Kate Seredy's The Good Master!
We walked the couple of hundred metres to our accommodation only to find the gates locked and nobody at home. Again, miraculously, the proprietor of the holiday lets next door was in her garden and realised what had happened, so she rang the landlady of this place, Angela (sloth a hard g, like Frau Merkel), who was round within a couple of minutes to let us in. She had no English, so sent for a very nice young man called Mark - son? Toyboy? Neighbour? - who did speak English and we were soon sorted. A very nice studio apartment with a shared kitchen, except we are the only people here, so not shared!
After a rest and a cup of tea, we set out to find the only restaurant in town that would be open. We ordered a sharing plate - allegedly for two people. Big mistake, and I do mean big - it would have fed, if not the five thousand, then at least six people. The proprietor did offer us a box for the leftovers, but when would we have eaten them? We don't have a microwave in Budapest!
Then we wandered slowly back to the apartment via the church and are now relaxing before bed.
