We stayed 3 nights in the amador de Los Rios at the start of May. It was in an excellent location close to 2 Metro stations that linkled to everywhere in the city. The room was clean and comfortable with the added benefit of a wide terrace that provided spectacular views across the city. The staff were really helpful and recommended a stunning local restaurant - TenConTen - which we would throughly recommend, although make sure you book. Really lovely stay.
