I'm looking for a reliable cleaner in the walthamstow area. it's a 3-bedroom house, but cleaning is only needed for the common areas (living room, kitchen, bathroom, and hallway). preferably once or twice a week — days and times are flexible. please note: i have an extra-large breed guard dog who's very friendly with people. she may want to have a quick sniff to say hello, but that's about it — she's calm and gentle. thanks in advance!
