We stayed in Goncalo's and Miku's flat over Christmas and had a wonderful time. Their flat is really nice, warm (it had under-floor heating throughout) and spacious. It's located within walking distance to restaurants, supermarkets, tube station and parks for the kids. As hosts, Goncalo and Miku were very responsive; when we reported that the washing machine was not working they sent someone over to fix it right away. Also, they provided a high chair for our toddler which was so useful. Overall, we had a great time and really enjoyed the flat!
