Overall positive experience, but also a few areas which can be be improved.
(+) Karl was a proactive, friendly host. He allowed us to use the washer to do some laundry. Helped carry luggage to the apartment. Also helped turn on heater in bedroom before we got back.
(+) Place was clean and tidy. Bed was nice and comfortable
(-) During our stay, London temperature was below freezing. However, the room heating was weak and Karl also requested us to switch off heating in bathroom when not occupied. This meant the bathroom & bedroom were quite cold/chilly! Perhaps invest in a portable heater & some curtains for the bedroom to improve the overall heating situation? Also, allow bathroom heater to stay on?
(-) The description of the place was misleading. Though the listing is technically accurate, it is not clear why a picture of living room is included when guests have no access. Also, there is no lift access to the unit as it is on Level 2 (lift only serves Level 3 and up)
