I enjoyed my stay in Kumail's apartment a lot. I visited Seattle for a conference in the Amazon meeting center. The location was great, just around the corner of the venue.
The building is charming and well-maintained. The access is via 2 passcodes, one at street level and one for the apartment, no keys needed, which was very convenient.
There were some sounds of the radiotors, but these did not bother me. Also the blinds were good enough to make the apartment in dark at night.
Location is great, just a walk away from the Pike Place Fish market, the space needle and the shopping streets.
