Absolute gem of a spot! Visited with my partner for our one year anniversary; Charo was very kind and gifted us a complimentary bottle of wine.
The apartment is very spacious (the balcony is lovely) and has all amenities you'd need for a longer stay. The beds were comfortable and AC was available across all rooms.
Charo was incredibly responsive and helpful, providing detailed instructions for check in, alongside offering great suggestions for a range of activities.
The location was perfect, a short 25 minute walk to the Plaza de España, Alcazar and the Cathedral de Seville. It's very convenient navigating the city with endless busses (if you need). It was also very straightforward arriving from the airport, a short 20-or-so minute drive and a 10 minute walk from Justa Station.
Very highly recommend, you won't regret it.
