Stayed for 5 nights with 2 other adults, the apartment is within a private courtyard with a 24hr reception and is right on the river, small play area in the courtyard with plenty of grass for any kids. Arrived to a pleasant welcome with 2 bottles of wine and a very large bowl of (rather delicious) cherries slong with coffee, tea, milk & sugar.
Apartment location was good, on the river but still only a 10min walk to the old town. Having never been to Poland before I wasn't sure what my expectations were, but the old town was lovely with plenty to see and do. Eating out is pretty cheap for really nice food, eating in was nice as well and eve cheaper, most of the grocery stores had a delcatesen area where fresh meat and cheeses could be bought, we found a large fruit and veg market and bought plenty to keep us going.
I would really ecommend staying in this apartment, close to the town centre without any of the noise, Anna will even organise a taxi to pick you up at the airport and you know that you aren't being ripped off with the fare (other friends that travelled on the same flight had a much larger taxi fare to go a shorter distance).
