This apartment is in an amazing location and looked very comfortable from the photos and reviews I read. The space is represented well in the photos but the main entertaining spaces are smaller than pictured if you plan on spending a lot of time in the apartment (just a heads up).
The Capital hill area was a ton of fun to stay in. Lots of shops, restaurants, bars, etc. There is a Trader Joe's up the street and delicious bagel's for breakfast in the morning right across from the apartment. We all felt very safe in the area as well (but mindful at night like I would be anywhere).
The rooftop view is stunning! Definitely, a nice place to enjoy a glass of wine in the evening and get a few beautiful photos of the city.
As for the apartment itself- I've definitely stayed in more comfortable spaces. My overall feeling despite the location and rooftop was "it was ok". It has everything you need but it felt very basic (bedding is ok, linens are ok, showers are ok, etc.).
We stayed in mid-August and the temperature was in the high 80s to low 90s. The apartment advertises AC but it's a standalone unit in the living room. While the space is honestly not large, the AC unit barely cooled the small living room space and didn't even reach the bedrooms.
I arrived around 5 pm the first night and the apartment was almost 90 F. because the AC was accidentally turned off prior to our stay. It took over 24 hours for the space to cool down to a comfortable temperature (this was with windows open, fans on, etc.)
I contacted the host regarding the AC issue and he responded very promptly! He was very apologetic and gave a lot of suggestions for cooling the space down (which we followed, it just took a long time) and he even refunded us for the first night.
While the suggestions helped, I wouldn't say we were the most comfortable for the remainder of the stay. The bedrooms sat around 76-78 and we had to have the windows open every night with the fan blowing on high to get some airflow (not a huge deal but the city is loud so it added to the noise etc.). We had to keep all the blinds closed during the day to lessen the heat coming in and even had the front door open anytime we were in the apartment to help get the airflow from the hallway.
My suggestion would be to stay here maybe when the weather is not as hot. I know Seattle isn't known for the super hot temperatures so it's safe to say the AC isn't needed often enough to warrant a larger unit. Should you need it, however, it's not going to be a comfortable experience.
Considering pricing and fees etc from a value standpoint, we would have preferred to stay in a hotel looking back on the experience.
