I'll start with the positives about Roman's apartment:
1) you get a comfortable bed with clean linens,
2) the apartment is very close to public transportation, supermarkets and 15 minute walk from the center,
3) the kitchen is fully equipped even with a dishwasher.
The negatives include not having an air conditioner and the street is quite noisy with the windows open. If you can sleep with no AC and with noise from the street - it's a great deal. We were expecting to have an AC, so we were disappointed.
