The owners/managers are very nice. Rafi came to meet us and also helped us get a taxi when we were leaving. The apartment is clean, but it's small and I would only recommend it to either a small 3 person family or 3 friends max. We visited for 3 weeks and I was happy to have the washer, and the apartment comes with cleaning supplies. Everything worked well.
The apartment is bright, as advertised, but the view is of the back of a building and an ugly cement courtyard, so I left the translucent blind down all the time.
It's quiet and close to supermarkets (3 mins walk) and coffee shops, restaurants, the Triana Market and the bridge into Sevilla (5 mins). Walking to the church in the center takes 20 mins.
Very functional and presumably safe. The building is not fancy, but for the price, the apartment is great value.
