Daniela's home is perfectly location for seeing Lisbon. It's right in the action and not massively impacted by the noise of the busy streets below. However...
Unfortunately the bed was awful and we struggled to sleep whilst there (ending our stay early) The mattress was old and compressed so you can't lie flat and the frame was so noisy that we woke each other up turning in the night. the bedding and pillows are old and warn and didn't smell fresh... it seems that lots of people have complained about this but despite that the rating overall is high so we didn't pay much attention. Daniela said the bed is being replaced on the 10th so I would check with them before committing to a stay.
We were offered the sofa bed in the lounge or early exit. I asked for a discount which was refused. Her alternative offer was to leave and get a refund for one night, when we still had 2 of 4 to go. Ultimately we were forced to stay an extra night so as not to lose money and left as soon as we could.
