The flat is conveniently located - a metro station a short walk away, a Velib station on the block, and tons of fantastic restaurants and bars both on the block and around the neighborhood.
The bed is super comfortable - it folds out into a large double bed. There is a small kitchen and table to eat on and a large bathroom. Overall the flat is very cosy, perfect for two people and very good location.
Carlos was a lovely host, very kind and accommodating - when we arrived earlier than anticipated he went out of his way to make it to the flat early and and make us comfortable.
My only comment, is that the amenities were a bit lacking. The linens could do with updating - the towels in particular need replacing, and there was only shampoo and hand soap - no body wash, etc. - however this isn't a problem if you travel with your own.
I also thought I would mention that the flat is a walk up to the 3rd floor up a very narrow (and beautiful) staircase. This was not a problem for us and really shouldn't keep you from staying here - just a word of warning for those who may have trouble with stairs.
