My husband and I stayed at West Seattle Cottage for a month and it was great for our needs. The cottage itself and surrounding neighbourhood are quite beautiful, quite, and well connected. We would definitely stay again!
Two things to keep in mind for longer stays: cooking is difficult. We just used the microwave because there’s only a single plug in hot plate and a crock pot.
The washer is one of those portable kind and can only fit a few items at a time. This was definitely not going to work for bedding or for clothes for two people. Thankfully we have family in the area and could use their washer/dryer while we stayed here. There’s also a laundromat very close by, but this will run you about 10 per load which adds up quickly.
