Although there is generally no shortage of accommodation in Bukit Lawang, if you don't mind where you sleep, if you have a particular place or room in mind, then you should book in advance. From late June through August, at Easter, and around Christmas, rooms are very busy with foreign guests, and most places will be booked up.

We have some accommodation recommendations below. We can book rooms and transport when you book trekking with us. 

We can also recommend accommodation booking according to your budget, location preferences, whether you want a room in a quiet location, and so on.

We would advise in general:

• room rates are entirely outside of our control, and the rates displayed on this website are accurate as far as we know, but are subject to change/increase by the guesthouse owners without any notice.
• most bedrooms have one large bed (double or king-size). These sleep two people, providing they are willing to share a bed. Extra beds are typically available but may be just a mattress on the floor. Only a few places offer more than one bed (twin room). You can also find family rooms, which are designed to sleep more than two people, but also have separate beds. The cheapest solution if you don't want to share a bed is just to take two separate rooms. 
• Air con is only found in Rindu Alam Hotel. Many guesthouses have fans in the room, and these will keep you cool enough (however in the event of a power cut, you will probably wake up!). Some guesthouses do not have fans, however these tend to be the more rustic wooden places, which are naturally cooler, so again it is not necessary.
• the usual Indonesian way of bathing is using a small bucket, which you dip into the 'mandi', a large container of water, and pour over yourself. The water will feel quite cold, but not unbearably so - it's good to cool you down after a sweaty day. Many places have a shower, but do not expect 5 star water pressure.
• if you don't care for the 'mandi', then many local people bathe in the river, bringing shampoo, toothpaste, soap, etc., to have a bath in the river. 
• hot water really isn't necessary, but can be found in a few places - Rindu Alam and Wisma Leuser Sibayak (not all rooms)
• nearly all rooms in the guesthouses have Western sit down toilets, but you will have to flush yourself, using the bucket of water and the mandi. Only a few have functioning flush mechanisms! Normal Indonesians use squat toilets, so don't expect to find sit-down toilets elsewhere. Toilet paper is not used, and is typically not be provided (but can be purchased for around 3,000rp per roll) - instead Indonesians simply use water and their left hand.
• generally do not expect to find toiletries, such as soap or shampoo in the rooms. These however can be easily purchased locally.
• beds should have a fitted sheet and two pillows with pillow cases and typically a blanket. A towel will either be provided or should be requested.
• there is no formal 'housekeeping' in terms of changing your sheets and cleaning your room every day, but the rooms are cleaned when you check out and if you stay more than a day or two, you can just ask for the room to be cleaned, for new towels, etc.
• laundry service for your clothes is available - just ask (and check the price, but it won't be 5* hotel price), this will be performed typically by hand, in the river. Allow 24 hours for completion.
• mosquitoes are an annoyance, essentially from dusk till dawn. All guesthouses offer mosquito nets, but they can often have small holes. If your mosquito net is broken, mention it to the guesthouse. If you are bitten a lot by mosquitoes, then you can by mosquito repellent locally, as well as buying anti-mosquito coils, which are burnt to produce mosquito-repelling smoke.
• generally room rates are very cheap, cheaper for Western guests than locals. Low room rates are subsidised by guests' purchases of food and drink in the restaurant. You have no obligation to eat or drink at your guesthouse restaurant, but it's worth trying it at least once.
