We really enjoyed our stay in Santiago, and Eduardo's place makes everything really accessible. We were able to find our way through public transit from Valparaiso and around the city on rented bikes. There is also a Sunday market just down the street.
The apartment itself is well equipped - full kitchen, comfortable shower and great views. When we were there, the place and two decks got way too hot during the day, but very comfortable when the sun went down. The pool was a welcome break, but good to note that it is closed on Mondays. The bed was too small for the two of us. We couldn't both lay on our back, and the photo is accurate that it will only fit one normal-sized pillow.
Eduardo was very polite and prompt with responses before and during our visit.
