The location of this cottage is very nice, in the Wicklow mountains. It takes about 40 minutes to walk to Laragh and a little over an hour to walk to Glendalough. I would definitely recommend to hike around the lake - the views are amazing. Unfortunately the cottage was not.
As other travelers have mentioned, there was no WiFi signal. We were able to connect to the router, but got a message there was no more prepaid amount left and we were unable to buy any. Contacting the host didn't resolve the issue. There is also no cellular signal - so you are left isolated. When you walk to Laragh, you can get a 4G connection.
The place was dirty - from floors to toilets - excrements from previous users still there. We cleaned them but that's not what we wanted to do on our holiday..
The beds were creaky so we were waking eachother up and there were no proper curtains, but I guess these things are a matter of personal preference.
What we found was not like the pictures or the description in the advertisement, and from our experience I would not recommend it.
