I think "6 guests" is a bit misleading -- the sofa bed is fine, but there isn't any mention that both bathrooms are only accessible through the bedrooms. Whoever ends up on the sofa bed needs to go up the stairs and sneak through a bedroom if they need a bathroom overnight. Not ideal.
The bathroom doors also come off their railings very easily -- one fell off and trapped one of us. I wouldn't recommend if you have children with you.
The location is great, and the space is well-maintained and nicely decorated. Diego was very responsive.
