Great location. Very easy access to donwtown. Pictures of the space are very accurate. The apartment was very comfortable and livable. We were there for a week, and it always felt like coming home instead on going to a cookie-cutter hotel room. Cathy was a really good host. She checked in by text periodically to make sure we had everything we needed. It was a very walkable neighborhood, with amenities close by -- groceries, drugstore, transportation, shopping, coffee shops (Starbucks, for this die-hard Seattlite!), wonderful ice cream parlor, restaurants, Wrigley Field, etc.
The only negative I can think someone might want to be aware of is the noise level. The apartment is very close to the El trains and they run frequently. The noise was not a negative for us because we also live in an urban area that comes with a fair amount of noise. We quickly tuned out the trains, but if someone is extremely sensitive to noise it's good to be aware. The very positive thing about the train noise is that you have a very short walk to the station!
