I was very impressed with the experience staying in this apartment. Not only is it very stylish, the check in process was super easy (using key pads and codes) and the host was communicative throughout. We were texting the whole evening of our check-in, including after we had settled in and were trying to locate the laundry (it's on the rooftop Terrace). The host also accommodated a slightly later check out given our flight time.
The location is a bit out of the area where all the major tourist attractions are, but very close to Almeda de Hercules, which is a great spot for drinks and a quick lunch. I think the location was great, personally, but just figured it was worth mentioning. Seville is a very commutable and walkable city.
Would recommend this place for people. The only real complaint is the upstairs bathroom is short for tall people - I am 6'2" and my girlfriend is 5'10". Luckily there's a larger bathroom with a taller shower downstairs.
