Alex's place was very comfortable and in a great location! We felt comfortable in the area, and had easy access into most parts of the city, either via bus or streetcar. It's walking distance to serveral restaurants and Dolores park.
It was great to have access to a full kitchen and fridge so that we could cook and store food without always eating out. The garden in the back was beautiful and cozy. We enjoyed sitting outside and relaxing over coffee in the mornings.
We didn't have much trouble with the bathroom being through one of the bedrooms, but keep that in mind depending on your living situation. The friends we stayed with we're fine to leave the door unlocked, and we were able to sneak in to the bathroom while they slept without much problem.
