The apartment is perfectly clean and it already has everything you need for a few days (toilet paper, shower gel, salt, olive oil, napkins...), so that you don't waste money in buying big packs of things you don't use completely. The host is very kind and helpful if you need some advice about Madrid. The only issue is about the boiler (for hot water): it has a small capacity and it takes a lot of time to reheat, but if you pay attentions (such as quick showers) you won't face any problem. The position is fantastic, very close to a famous street for night life, and also to an underground station (the underground network is very efficient, you can easily reach the city centre in less than 20 minutes).
