We have mixed feelings about the flat.
There are 3 major upsides: (1) the parking, which is absolutely vital in Sevilla, (2) Lolla, who checked us in and gave us great tips and even let us leave our luggage much earlier than the usual check-in, and (3) the location near Alameda de Hércules and within reasonable distance from the city centre (Plaza de España and Real Alcázar).
At the same time, there are several issues we faced that didn't help us at all: the Wi-Fi never worked properly during our whole stay and we were forced to resort to our data plans on roaming (not ideal!); the water in the shower never heated up properly and all we had were, at best, tepid showers; the bathroom is tiny and it takes a lot of effort not to bump into or elbow something while in it (plus: the bath mat is always soaked and seems impossible to dry).
This house is a good alternative for young couples with a very (very!) easygoing attitude towards life who don't mind walking 30 min to the main monuments and are in need of a place with parking while on a tight budget. I wouldn't really recommend this listing if you don't fit in this description.
