Sonia was a really lovely host, and available to answer questions at any time. The issue is really with the area, which I just think a potential guest needs to be aware of, especially if you are a single female traveller.
The street is on the edge of a housing estate, notorious as being one of the poorest in Spain (look up Las 3000 Viviendas). The streets adjacent to the flat are lined with rubbish that hasn't been collected, and hollowed out foundations of flats, and homeless people wandering the streets at night. There was a shanty house on the corner with people burning rubbish in the front garden. On the weekend in the night I could hear of lot of noise from the neighbours and a lot of revving.
It is a very dodgy area, which is fine for some people, and perhaps fine if you aren't arriving with a large suitcase, obviously looking like a tourist. I just think it’s important to make an informed decision, especially if you are travelling with laptops or cameras, or anything that you would be worried about losing. To confirm, nothing happened to me, but it is undeniably an impoverished area that sees next to no locals from the rest of the city, let alone tourists.
The flat is only 1 road away from the main road, meaning that the time between getting off the bus and arriving at the flat is relatively short, which is a plus. I took a bus into the city centre twice the daytime, but actually it would always end up taking about an hour to get in the centre because the buses aren't that frequent. What this essentially meant is that the cheapness of the room is offset by getting constant taxis to and from the apartment, as I was told multiple times by locals that it would not be safe for me to arrive alone at night, and it really felt that way. I am not someone easily spooked (I often choose the cheap option over the nicer option) but my gut was really warning me on this one.
Location aside, the room was great. The bed was super cosy, and there was a real duvet which is so rare in Spain and I loved it! The shower was hot, and the kitchen had plenty of space and utensils and basics like oil and salt. They have two fridges which was great. I really want to emphasise I am not saying, “don’t stay here!” rather, you should be aware of the constraints and risk of the location (which would have affected my decision, had I known).
