we stayed in the apartment for a total of 5 nights. all in all i can say that 2 nights was too much, because there were a few points to complain about:
1. the terrible consistent smell in the bath, which we had to face several times during our stay
2. On the bed and the pillow were several fuzzes.
3. The bath carpet and towels looked just gross - full of undefinable spots that looks like vomit.
4. After 2 minutes in the shower there was no warm water.
In our opinion all these inconveniences combined were too much for the high price he had to pay.
What worked out very well is the communication with leeways. He responded in 15 min and was very helpful all the time.
