Alfredo was excellent to deal with. The apartment was exactly as described. The bed in the bedroom is great as well as the pull out sofa, it's not your normal spring type mattress and probably the most comfortable sofabed I've ever slept on. The kitchen is well stocked. Alfredo even went out to purchase more laundry detergent for us. The washing machine is a nice feature, but note the dryer is not separate and does not dry the clothes like we're used to in North America. But he provides a drying rack so problem solved!
The only reason I gave it a 4 star was that we had to leave early due to an incredible heat wave that hit London the week we were there. Unfortunately Alfredo's place does not have air conditioning. He was very generous to offer more fans to help. This is more than likely a rare incident and had the weather been even a little cooler the place would have been fine.
It's right across the street from Caledonian Road tube station on the picadilly line which is very convenient to a lot of sight seeing areas. It's also very close to 3 different grocery stores, nice for when you just don't want to eat out.
