My stay was great! Having a private entrance is convenient and the room was just perfect. Very spacious, also for a big suitcase. Everything was spotless clean, especially the bathroom. I really enjoyed the big shower! The location is also very good, you can reach Castro by foot if you do not have a problem with a 15-20 min walk.
The only thing you might wanna consider is that the room can be a bit noisy because of the freeway, which is pretty nearby. Also, you might notice the kids in the morning in the next room. Wasn't a problem for me 'though, since I needed to get out early anyway.
Bottom line: I had a great experience, would definitely come again!
