It was a beautiful, convenient and private stay at Byron and Gerard's place. The description on Airbnb is accurate and as expected, all the accommodation was prepared with clean towels. Though the check-in was 2 pm, Byron was very generous and accommodated an earlier check-in for us. Just one subway stop from the tourist area (Sol station), the flat was accessible to subway, local dining, grocery shopping and even train station (Atocha station), yet the suite was private and quiet.
Overall, it was one of my best Airbnb experience ever. Thank you, Byron!
