Really great place - close to the station, next to a nice lake. The room itself was great value for the money - great size and well heated. Only slight downside was the wifi which was slightly spotty. Be careful if you rely heavily on it (eg. if you wanted to work from there), but nice amenities with a desk and fully functioning tv with firestick.
Definitely recommend for anyone staying in the Erith/Abbey Wood area on a budget.
