My family of 4 slept comfortably in the big room. There are 3 rooms upstairs that share one shower/bathroom so sometimes it’s occupied, but Cristina let us know that we could also use the downstairs bathroom.
Uber drivers were plentiful in this area, and had no problem finding the house.
We self-checked in after 4pm, took an Uber driver to Buckingham Palace where we explored Westminster. We met Cristina and her husband when we returned after 10pm. They’re a happy, friendly couple, and we would love to have had more time to get acquainted, but our kids (and us) were exhausted from our quick tour of London. We slept soundly and comfortably, and used Uber app to get an early morning ride back to Heathrow.
