We stayed in the Amazonas Inn four nights. The service is good and the staff is friendly. It was an OK option between day trips in Quito and reading reviews it seems it has been refurbished. We paid 35$ for a double room that was spacious and full of light with two balconies, wooden floors throughout, cable tv, wifi(that works!) and hot shower.
However the rooms in the first floor are quite noisy once the breakfast service begins (7 am) and the matresses in the first floor are extremely hard, we wanted to change rooms but the ones on the second floor have tiny little windows. Also the sliding doors of the bathrooms do not close and the shower was outdated but the water was hot.
The breakfast was included, enough but not plenty. It included toasts, butter and jam plus eggs one day and salad fruit the next one.
The area is very convinient, full of restaurants/bars(Plaza Foch) and travel agencies. Although during the night it changes (hikers) but there is police all around. It seems it is changing in the last couple of years.
Overall this hotel was OK. It was a cheap option but two nights I couldn't sleep properly.
