We were four people arriving at 3 different times and Lex handled it with aplomb. He was gracious and very accommodating in all requests.
We all loved his house. The location was amazing. Bustling Camden Street with its restaurants/pubs/stores is literally a one minute walk away, yet the house is quiet and comfortable. There is a cosy back patio area, but sadly we didn't have the time to utilize it. It really felt like home and everything we needed was there.
The walk to the touristy areas (St. Patrick's, Brazen Head, Christchurch Cathedral, Dublin Castle, Temple Bar, O'Connell Street, Grafton Street) are all less than 20 minutes.
Really a great place to stay and we couldn't have been happier.
If it's available, I would just book it.
