The apartment is really cool! The front room has 3 balconies over-looking Barrio Alto.
The location is not as it says on the map, it's much further out than I expected, its the top part of Barrio Alto.
We were a big group, 17 people... we did make it work but it wasn't really ideal. I would say the apartment is great for groups of 10 or 12 people (if you want a room each).
There are 3 bathrooms all running off a tiny boiler so you cannot have showers at the same time.... to be honest even if you do have a shower when no one else is the water dribbles out.... get a new boiler if you want 17 people staying at once!
We had a great trip and the house is amazing... it's just not set up properly for very larger groups... in my opinion
