The good:
The location of the apartment was great - lots of good bars and restaurants around and a reasonable walk to other attractions in the city. The apartment was nicely decorated, had good air conditioning, a washing machine, and a well-equipped kitchen. The hosts were accommodating with allowing us an early check in and giving us a thorough explanation of the apartment and recommendations in Sevilla.
The bad:
Bugs - on two occasions, we saw (huge) cockroaches. There were also lots of ants in the living room and bathroom. My wife is really scared of cockroaches, so this significantly decreased our comfort level and enjoyment of the apartment. We contacted the hosts about this to see if they could do something to treat for at least the roaches, but they never responded.
The pool - while these are building rules and not the hosts’ fault, we felt the pool rules were really restrictive. For instance, it closes from 3-5pm, which is generally the window we wanted to use it (when it’s extremely hot and other shops and such are closed). You’re also not allowed to wear sunscreen in the pool, which makes it totally impractical to use for much of the day.
Overall, while the apartment itself was really nice, the last two points made it feel like we weren’t getting the value we were paying for.
