Me and a friend stayed a week in Iker's apartment and we had a good time there. For 4 people you have plenty of place in the apartment, with 5-6 people it can be a bit crowded but managable. The apartment is just as described, very close to the metro, very well equipped so you can prepare your own meal if wanted. Also there is a beautiful view from the terrace of the 15th floor. Very close to the metro, supermarket and bakery just 2-3 min walking distance. Only the internet was slow while we were there.
