The apartment worked well for 6 of us (3 couples) as there are 3 bedrooms and 3 bathrooms (2 en-suite). There are extra single beds in each room and sofa beds in the living room so it can sleep more but it would be cosy.
The best feature for us was the adapted bathroom with a roll in shower, shower seat and grab rails for those with mobility needs. Adapted bathrooms are hard to find! The whole apartment was step free but the entrance ramp would be too steep for most wheelchair users to manage on their own.
The host Karina is friendly and lives very near by so came over quickly when we had a question. She does not speak much English but more than the Spanish I know (not much).
The location is residential so it is good if you don't want to be in a touristy area. It is far from the metro but not bus stops or taxi ranks.
