Good aspects: The apartment and all the rooms are very big and well furnished. All rooms and living room have air conditioning, which is very important in summer. The apartment have balconies with great views. It is a 8 floor and has elevator. Igor was very helpful and tried to solve all our requests.
Bad aspects: We had problems with two beds of one of the rooms. They had a bed structure made of a flexible metal net which caused the guests to "sink" in the mattress when they were sit or laid down. They ended up sleeping in the sofa bed of the living room (which was very good). The fridge didn't work well since it could maintain the temperature of food but couldn't make it colder.
Overall: We were on a business trip and in general we liked very much the apartment. It is great for big groups since it has 2 bathrooms (one of them very big), big rooms (with tables and chairs) and a very big living room with a big dining table. The wi-fi worked perfectly even with 6 people connected.
