Great appartment With cosy vibe and little balcony. Also roof top terrace With pool (although unfortunately it turned out later that that was closed end of March).
Good location in San Telmo, on walking distance to the market and with some very nice restaurants on your doorstep.
Only lesser point: slightly noisy refrigerator (which could bother you if you like your silence). It does turn of at night! Kitchen for the rest is nice and has all you need for few days.
