Great stay and location. Stayed with two friends for a quick visit to London and it was super easy to get to main tourist sites by car or walking.
Just a reminder for American travelers like us who aren't used to the narrow European staircases: you do have to go up some stairs and there's a tight turn. We managed between us with our large luggage, but I wouldn't recommend it if you have any injuries or knee issues. However, Eduardo has some staff that can help depending on your timing so check with him. We unfortunately arrived and left at off times. Another thing to note is that the general area is filled with cigarette smoke so our clothes kind of smelled like it.
Otherwise, it was a safe and secure area. Eduardo was great and replied to all my questions and the flat is true to the listing. It's above a restaurant and there's a grocery store within walking distance. Thanks!
