We stayed in the Sth Ken flat for a week in July. It was in a very convenient location for the museums in the area and for the Sth Ken station which services three underground lines. Flat was clean and had everything we needed. We booked it at short notice and check in was somewhat delayed but Francisco and Manuel accomodated our request for late check out. We should mention that the common areas of the building are currently under renovation and there is some noise coming from works during the day. The train tracks run under that building so you could hear some noise from that too but not loud so it didnt affect our sleep. The shower pressure is weak. We are however still quite happy with our stay at this flat.
