the place was cosy and clean, unfortunately very cold for me or maybe not warm enough. I have arrived an hour earlier than they expected me and the heatings weren't on. it was freezing outside that day ( -5) and the apartment didn't warm up properly. luckily there was a spare blanket I could use downstairs. the upstairs radiator wasn't working properly. it wasn't warm enough. I have mentioned to the owners a few times who kindly decided the leave them on the whole night (it was mentioned initially they were going to go off at 11:30pm and back at 6am). if you decide to stay during winter, bring enough warm clothes to wear indoor.
other than breakfast was good, location is perfect and Marlow is a beautiful little town.
