Pros: Overall it was very safe (multiple locks to get to the unit). Cleaned well. Location was great (felt more residential, not too touristy). Close to metro stops (20 min walk+metro to all the big sights). Also literally right next to a grocery store. Kitchen was well stocked with utensils.
Cons: Having “off service” AC in 90+ F weather was really difficult (not much air flow). The shower and washing machine leak water onto the floor. The space was pretty cramped for 6 people, but we made it work.
