We stayed in Fernando's place in August 2019. The location was great for a family of four in that it was close to a variety of restaurants and other amenities, within easy walk to several tube stations, near major attractions, but outside of the busy (and noisy) major tourist areas.
The interior of the space was well laid out with the common areas on the main floor and the bedrooms downstairs. We had plenty of space for our needs. The place does look a bit beat up and dated in most respects including furniture, bedding, towels, linens, etc. Nothing that was intolerable, but it is probably time to refresh the linens and bedding and have a handy-man (or the British version thereof) come and fix some light fixtures and other aspects of house.
