Hotel Simon is in a great spot. In the old town near everything. Staff are friendly - they look after your bags, call you taxis etc. It's a 5* location.
The hotel is historic, but basic - very basic. It's clean. It's got good wifi but no TV. Probably a 1* room.
We had a ground floor room - they are very basic. Probably the most basic hotel room I've stayed in for many years. Room 111 had no windows - but no street noise either. If I went again I'd stay upstairs.
Having said that - it was fine. We spent very little time in our room. The bed was passable. Seville is fantastic - go outside. If you want to spend your money on tapas and beer then flop home. Hotel Simon is fine.
