This flat in the Barbican was at an excellent location. Hosts were very responsive. Only negative I faced was the inconsistency in the Wi-Fi, which made it difficult to work. If having reliable fast Wi-Fi isn’t a problem I would always recommend this flat, so close to public transport, very walkable to nearby tourist spots.
Just know this flat is essentially 4 stories, the entrance leaves little room to put your stuff since it’s a doorway and stairs. Still it was great, the beds were comfy. Would stay again if I didn’t also have to work.
