I came to bukittinggi with a friend at 8 pm and didn't book any accommodation. We only have the guest house's address and some faith that we can get a room in the middle of the week, and thankfully we did! We got a double bed room and bathroom with hot shower (important for bukittinggi relatively cooler climate), we didn't get the tv but we thought that who want to watch tv while traveling, right? well, the tv actually can help you to mask the sound from next door or from the lobby or from the mosque down the road. The acoustic in the middle room we were in was good, we almost can hear everything. But that don't make us disappointed! because the room and bath was clean, they provide internet wifi, unlimited hot water, coffee and tea as much as we like, and great advices on getting around town. Ling and her parents were very friendly and helpful. They were open to chat and have great recommendation on places we need to visit plus how to get there. they also help us getting transport back to Padang. It was a delightful (albeit short) experience in bukittingi with this guest house!
