We stayed in Walter's place for 3 nights, and we had the enjoyable time there. The place is very clean and comfortable, and the location is about 2km, a walkin distance, to the city centre.
Thomas is a great host and thoughtful, who prepared everything before we arrive, eg. Milk for making coffee and tea as the shops all shut at the Chrstmas eve. He waited for our arrival and explained everything to us in a great detail. When we had the tour next day, we knew what we were looking for. Thomas also booked taxi for us on the day our departure because this is always difficult for travelling in a foriegn language country to talk someone over the phone. Thanks Thomas!
