Marco & Alena could not have been lovelier or more welcoming. From first contact to check-out, they were terrific. The new building is very clean and well-lit in its public spaces and the lift was a boon when coming and going with my luggage. The flat is immaculate and stylish and the guest bedroom and bathroom are very spacious and offered everything I needed in terms of drawers and closets and table and power outlets. The shared living room/kitchen is filled with light (as well as some of their own art) and the balcony was a nice retreat to relax on.
The immediate area doesn't have too much going on- save for the very convenient Tesco across the street- but Clapham and Brixton are both a short bus ride away and there is no end of excitement in those neighbourhoods and the bus stop is practically at the front door. (Conveniently, a 2-minute walk away was the 59 bus that goes straight through Central London up to King's Cross.)
In the end because I was out every night at the theatre, I didn't actually cross paths with my hosts all that often, but when we did they were there to ask how things were going and to offer any tips I might like about where to go and what to see. And the guest room had several guides and books about the city for me to peruse.
I have been very fortunate using Airbnb and Alena & Marco's place has raised the bar that much higher! Thanks for everything!
