We (2 adults and a 5 year old) had a great time. More than enough space, tho 7 might be a tight fit.
Location and price/value is awesome. The little one had fun with a provided kickboard.
Otherwise everything as described and as on the photos. The place was spotless clean as we arrived. The kitchen is small but well stocked.

No problems getting in using the instructions. Hint: if arriving in darkness use a phone/flashlight to find the keys of the lock.

Maybe the only quirk was the spiral staircase.

Would definitely stay again.
