We had a great time staying with Lisa! She was very responsive and checked in on us multiple times to see if everything was good. The apartment is really comfortable for two people, and since we both are not that tall, we had no problem walking around or with the shower.
The kitchen has all the essentials with the exception of a stovetop, but there are enough restaurants in the area to feed you anyway.
The connection to downtown Seattle and Seattle Center is really great and easy, there is a train going every 10 mins and multiple busses to take you all around Seattle. Also getting to and from the airport is very easy as you only have to take this one train.
As others have commented, if there are guests in the upstairs apartment it can get really loud. During our stay the upstairs family had a dog that was howling during the day and kids running around in the evening, but since we were out most of the time it didn't really bother us too much as they went to bed around the same time as we did.
We can absolutely recommend staying with Lisa! It was overall a great experience and a fun time :)
