I was many times in Ibis Budget Whitechapel London, which I like very much. It was to me the first time to stay in budget Ibis line outside UK.
I was a little sceptic in my expectations when I booked Ibis Budget Sevilla, but because I used hotel only over the night I was not disappointed.
Only problem is if you don't come there by car. Using local buses could be an advantage. Bus stop for hotel has three different names: Avenida Kansas Talbot, and Avenida Kansas with two other words added (I forgot those words). It is not a big problem if display on the local bus is working - you must follow what is written on it and push stop for the next stop when the right name of the station appears. If display doesn't work (it happens in 20% of cases) , you can ask a driver to stop in the stop for Ibis - and hope that he would do it... If bus driver speaks only Spanish, then you really have a problem (it happened to me ones).
Hotel is nice, clean, worth of money, ask for a triple room, in middle of June outside of hotel there were many orange trees - offering you a free breakfast.
Staff of the hotel is efficient, normally is nobody at the reception, but comes on call.
If you want to spend for a night 30 or a little bit more for two or even three persons, I would strongly recommend this hotel.
