Not suitable for 4 adults and should not be an option! The sofa bed really only accommodates 1 adult, or an adult and small child. Additionally, there was an extra set of sheets (fitted & flat), and a comforter for the sofa bed, but no extra pillows or pillow cases.
The drains in the bathroom sink and shower were draining horribly slow (was standing in dirty water after a shower!) 😒. Was able to lift the stopper in the sink, but for the shower, had to almost remove it.
Certain things could be improved for longer stays, e.g. there was only ONE dish towel, and towel set for 4. While I believe a change of linen, etc was availability if needed, 1 dish towel seems a bit too minimalistic.
Was surprised to find there was no coffee/tea, sugar, salt, etc.
Overall experience was good. Apt was clean, very nice and well laid out, small but not cramped. That said, the host needs to provide just a tad more comfort and convenience.
