Ellen & Mark are offering a cozy, functional space in a great neighborhood. Everything in the studio had been well thought-through, and it's abundantly clear that they are concerned about the needs their guests. Ellen is lightning-fast with responses, and her tips definitely helped the trip run more smoothly.
There are good restaurants / grocery / café within just a few blocks, and access to downtown Portland is extremely simple (I commuted every day via public transport with no problems).
