The hotel loaction was excellent - 7min walk to the closest station, 15min walk to South Kensington and its museums, and roughly 20-30min by tube to amy main attractions in London.
The hotel was just off the main street which means the noise was moderated however they were doing works during our stay and builders were on from 7am. Because of the works, the comfort was inconsistent from one room to another - our deco/comfort, especially in the bathroom were really outdated; trace of mould here and there, the water pressure and temperature were only mild and heaters not properly working in January(!) while the friends we were travelling with had brand new bedroom/bathroom.
That said, everything was clean.
The room had no plugs near the bed whoch makes it tricky for phone and alarms. And isolation was poor - you could hear people above, aside and underneath.
The breakfast had a full range of ingredients however they close it 20min proor the time indicated without apology and the people in charge forbid us, rather virulently, to group a couple of tables together, in a corner of the room, to eat with our friends. We offered to place them back where there were but they said no categorically for no apparent reason and with bad manners so we finally had to ask permission to reception.
