Marta is a great host , friendly and informative and very prompt in communicating. She had no problem with late check-in. Space is great for a few days in Lisbon - very near public transport but if you have the energy to walk to center - it can easily done in 15 minutes.
I found I cooked very little in the apartment due to its proximity to some lovely bakeries and restaurants (5 min walk) . Crusty bread/ Croissant etc with cheese, an expresso and freshly squeezed orange juice - a mere €2.75 every morning. Ramerio - the famous seafood restaurant is also on this street as well as some very cheap beauticians. A supermarket is 5 mins walk uphill from apartment and is open until 9pm.
Finally apartment was very clean - thanks Marta
