Oasis Hostel Seville advertises itself as the peaceful alternative to the Oasis Palace's party atmosphere. Sadly, rowdy guests in the shared dorms proved otherwise and made for a terrible stay. Still, I won't rate the hostel on its guests.
The hostel staff were friendly to me and tried their best to be accommodating. This can't be said for their treatment of all guests and even their good intentions led to poor service for me. With a heatwave that taxed the AC the rooms were too hot, inadequate curtains allowed tons of street light in, noisy roommates after quiet hours prevented any rest, and a broken drier caused laundry to take 12 hours more than promised- with no refund, discount or alternate option beyond cursory apologies. When you only have 36 hours in a city it's helpful to know if you'll have clothes in the morning or after 9pm as you plan your visit!
The facility is new, has good water pressure and even hot water, a great location, and should have been my best hostel to date. Unfortunately, I'd have traded all the new appliances for more professional support and less obnoxious roommates. This is a great place if you don't value sleep and don't mind helpfully oriented but uninformed staff. Even on my last morning I was incorrectly directed to the airport bus a block and a half from it's actual pick up location. Again, loved the idea they wanted and were willing to help, would have preferred they actually knew what they were doing.
