Juan and his flat are both great. He welcomed us amazingly and gave us really good recommendations as well as always being contactable at any time if we had any questions.
He let us use his kitchen (fully equipped) and we shared the house (and bathroom) with 1-2 other people. It was all very clean.
The location is great- close to 2 different subway stations (5-10 min walk) that take you directly to the centre in 30 mins.
The neighbourhood might not look the safest at first but my boyfriend and I had no problems at all and enjoyed seeing a different side to island :)
Would really recommend it to any friend.
