We stayed at Miguel and Monica's for 3 days. The check-in instructions were really clear and their flat is very clean. We didn't see them a lot, but Monica was really nice to us, and very available if we needed her. The flat is conveniently located if you're planning to go to the Olympic Park, and approximately 30 minutes away from the city centre. Overall, we really enjoyed our stay and will definitely consider coming back if the opportunity presents itself again!
