Avoca House Hotel has a delightful gentleman named Sean taking care of it and its guests. Sean greeted me when I arrived (later than he expected; my plane landed at 9 pm and he was expecting me to show up at the hotel at 9 pm). The directions I got prior to arriving got me to the hotel with no problem, and Sean carried my luggage upstairs for me, opened the door to the room, responded quite politely when I thought there were no towels (there were towels; I just didn't notice them after that flight I had). He made breakfast every morning and remembered exactly how I like my breakfast cooked. He was pleasant and polite at all times, and, when I left, he carried my luggage down ALL the stairs to the sidewalk for me.
My room was clean, quiet, and quite comfortable (I didn't spend much time in it; I didn't go to London to sit in my hotel room). Sean made sure the room was clean and neat each day.
Would I stay at Avoca House again? You bet I would. It was a lovely place to spend the week I was in London! It's outside of central London but is very accessible via the Tube (there are probably busses that go nearby also, but I didn't take the bus at all so wouldn't know), and, for all the hard work that Sean puts in, the price is very reasonable.
