I was greeted by Susana's husband at my arrival, and he was very nice and helpful. Susana was a mere phone message away and everything I asked for (mostly information) was promptly given.
The apartment is simple, yet very cosy and well supplied with all essentials. Honestly, I woudn´t change anything about it, it was just perfect for my stay. The host supplied bed linens and bath towels and even some bathroom essentials like shower gel and shampoo.
Also in the kitchen you have everything you need, from american coffee and tea to a fresh water bottle in the fridge, and also some basics like sugar, salt, garlick and pepper. They were also kind to offer a local delicacy (some olive oil cookies...? They were awesome).
If I ever return to Seville I'll certainly book this apartment again. Highly recommended!
