I simply don't have words to describe the hospitality of these two (Ray and Ivo) -- they spent time and time chatting to us and giving us advice how to plan our stay in London even when it was quite late in the evening. Everything we had as requests (early checkin / late checkout / amenities) were fulfilled completely.
Not to mention the coziness of their home -- at some point I felt like I wanted actually to live in a home like theirs. And it was spotlessly clean all the time!
The location is also great -- you have everything you need in the area - parks, shops, pubs and a underground station just outside the building.
Definetely staying there again if visiting London again (South West 4 2018? Who knows :))
