Would definitely recommend this apartment.
Good points: excellent location, very helpful and responsive hosts, lovely (if compact) apartment which was very quiet internally, spotlessly clean, good quality cot (with linen) and high chair provided with no trouble
Less good points: kitchen area is v small, the spiral staircase needs supervision for young kids (ours are 2 & 4). Neither of these were particularly problematic.
We had a great stay overall.
