I had a great time during my stay. Peter himself was off due to business but his wife Jo is such a lovely person to stay with. Almost invisible but there when you needed her. The location speaks for itself. Tube stations Marylebone or Baker Street are so easy to reach by foot.
But if you want to see more of London you need to take the red double-decker busses London is famous for. It takes a little bit longer but is more fun. Just go up to the second floor of the bus and enjoy the view from the front seat. Bus stops Rossmore Road and Lisson Grove are very close to the location.
What I would like to mention here is that during my stay the adjustment knob of the radiator was defective. The radiator was heating at full speed and therefore the windows needed to be opened all the time for a good room climate. The weather during my visit in May 22 was superb so that it wasn´t such a big deal for me.
The other thing I would like to point out is the mattrass´ degree of hardness. It was very soft. If you like more firm matrasses you should bare this in mind.
Would I recommend? Sure.
Would I come back? Absolutely.
