You love it or hate it. It swings largely on the attitude of the owner. A clear advantage is that it avoids flatshare power struggles: it's clear who's responsible and in control. Also you may be able to negotiate quite short periods of stay. But it possibly can never feel like your own home, simply because you can't abuse it in the way you would your own accommodation. But if you can find one of those properties where the owner has done it for several years and is in touch with nearly all their previous tenants, then it might provide that touch of support that you need on the odd occasion.
