The apartment was very good and very clean, it was having all the necessary things, clean towels and sheets, even shower gel and shampoo in the bathroom.
Elisabeth could not be with us the day of the check-in, but her mother was there to attend us (both can speak English). We could see Elisabeth the last day when we were going to leave. They are very welcome and nice persons.
We visited Madrid on August, but it was not a problem as every room had air conditioning, except the sitting room, but it is connected with one of the bedrooms.
Kitchen is okay, you can cook there and it has all the necessary appliances. There is only a small window, so I would not recommend cooking big meals in summer (it was not a hot kitchen though).
To be honest, we did not cook at all as there is a lot of places to go for having lunch and dinner.
I really recommend to stay in this apartment :)
