Kristina and David always reply very quickly and they are very helpful indeed:)
The location is perfect. Very close to 2 underground stations and buses are all around.
The water in the shower is quite small and for the taps you need to wait for quite a long time for hot water to come out. And We had a very noisy neighbour (every morning we were woken up by their door) so I guess sound insulation may be a problem.
But other than these we had a very nice Xmas trip and we definitely will be back soon:)
