We were 3 people and we stayed for a week in Michal&Michaels place. It is our fault but we did not realise that the apartment has no lounge or separate dining room area, and no dishwasher.
The lack of a recreational space became a burden as we had no where to relax together to watch television, for example and were left with just sitting around a kitchen table with no view out or windows in the area. The balconies are not useable for sitting, just standing.
We were there for 7 days but given only one tea towel for the kitchen and no hand towel for the kitchen. This was not hygienic. Our bath towels and bath mat were not replaced for the entire week which was also not hygienic.
The location was great but also reflected in the price . The BNB we are staying in now in Krakow is half the price, just as well located and has a large lounge, dining and kitchen open space with a dishwasher - much more enjoyable. I think Michal & Michaels apartments are converted from a much older and different building ,and while the bedrooms were large and the beds comfortable the space in awkward and not comfortable overall.
