Bring your own transformer for US/UK to EU plug, shampoo, and laundry detergent. Also, there might be construction going on while you're there, but never too early in the morning. The location is pretty great, located near a lot of buses with cute views on the two sides of the house. It's very well decorated and overall, a nice place to relax in after long days of looking around.
Just beware of mosquitoes if you leave the windows open. They are vicious. Leave the fan on overnight or you will wake up covered.
