I stayed at the GuestHouse for a week-long holiday, and was generally happy with the stay. The location was perfect, being a walkable distance from everywhere. However, the description is not as accurate as it should be.
There was no in-house laundry service - the paid service was expensive, so the closest laundromat was 10-15 min walk away.
Although there was a lift, you still have to climb a small, narrow flight of stairs. If you have a large/heavy suitcase or need accessible accommodation, this place might not be for you.
Finally, the mattress felt too soft; almost worn as it dipped in the middle.
All in all, for the price, it was a great stay.
