We loved this little subterranean oasis. It was remarkably quiet, homey feeling and comfortable, with a dash of charm. We enjoyed the idiosyncratic entry and the feeling of arriving at a little hideaway whenever we returned to the apartment. It's a good value and a great location, just blocks from restaurants, Portobello Road, with a cafe less than a block away. The only issue we had was a musty smell in the space, that was largly remedied by opening the front and back doors for cross ventilation when we were in the apartment. Helena also went out of her way to try to remedy this issue, once we told her about it, including delivering and installing a new large scale dehumidifier in the apartment, before we left. Really very charming and very reasonable. Helena was attentive and helpful.
