Rey's cousin, Magaly, made us feel very welcome and waited for our arrival even though we were a little late. She gave us a quick tour of the apartment and basically told us to make ourselves at home - with free access to the kitchen supplies.
The apartment is well-located, right above the tube station. There are also buses that go to the city centre from bus stops nearby. The building also has an elevator - good for travellers with heavy suitcases. There are supermarkets and several food options very near the apartment too. Would recommend!
