Overall, this apartment in beautiful Sevilla was a great place to stay. The location is stunning, within 15 minutes walk of the cathedral, Real Alcazar and only a little further to get to the Plaza de España. You really need your climbing legs on for this place, as the stairs are steep and you will end up going up and down them a fair few times. However, the benefit of getting to spend summer evenings sitting on the beautiful balcony, watching the streets below and making the last of the warm summer sun is definitely worth it. This place is spacious for 2 people (as we were) but would be fine for 4 (although the lack of privacy in the main room on the 1st floor would be an issue for some).
A few little bits that are worth knowing. Firstly is that the boiler wasn't working properly and the check-in agent told us that we needed to press a manual override button to get it going, this meant that on a couple of occasions we had to run up 3 flights of stairs to get the warm water working for a shower. Not a massive problem and it may now have been fixed, but worth knowing nevertheless.
The shower downstairs needs some TLC as the big rainfall head wasn't working that well and the shower tray had a tendency to fill up with water. Also, the oven isn't a proper oven, it is a microwave/grill combo (which actually worked fine to cook a pizza) but might not be great for cooking a complex meal.
However, the main thing that is worth re-emphasising is that the parking space is super small. We just about managed to squeeze a hired Audi A3 into the space but it got scraped by the car that was parked in the neighbouring space. Incidentally, the space next door has a massive VW that completely fills the space so needs plenty of maneuvering room. If you're a fairly confident/competent driver it is OK to get down the ramp and into the parking garage (relying on your car lights as there is no lighting underground). If you do park here, our advice would be to get a smaller car than we had and to park it as close to the wall as physically possible (you'll have to get so close you end up climbing out over the passenger seat). Also, make sure you have good insurance (particularly if you're in a hire car).
Overall, this was a great place to stay and we would recommend it :)
