Charming top floor flat on the Boulevard St Germain, with the most amazing bakery just downstairs. Fantastic location right by Solferino metro, and you can see the courtyard of the Musee d'Orsay from the corner of the block.
We had no problems with the stairs- even the 5 year old managed them fine- though they are very narrow (it is a service staircase). The flat was light and clean, well heated and with a good shower. The two bedrooms were a good size, eclectically furnished (no identikit Ikea furnishings here) and both have a view to the Eiffel Tower. This made our trip- the kids were delighted that at night it flashes and twinkles every hour! Alexandra's mother also recommended to us a walk along the Seine to the Eiffel Tower, which we really enjoyed.
I would recommend this place, so long as you don't have small children (lots of stairs and an unlocked 6th floor balcony in each of the bedrooms) OR if you are intending to cook. As the kitchen is really only a table with a microwave and a few plates, cutlery etc. You will need to wash up in the bathroom sink downstairs. This served us fine for the few simple picnic meals we ate in.
We found our communications with Alexandra very smooth and friendly, and her mother (who met us on arrival) extremely kind and helpful. We would definitely book this place again.
