We really enjoyed our stay. The patio is actually bigger than it looks (!) and it was great for coffee in the am. Both bedrooms had comfy beds and since they're on different floors which was nice for us to have some space away from our kid. Location is amazing - you're on top of everything. I mean 1 min walk to 5 different restaurants/bars/gelatarias. Not sure if it's the thick walls of an old building or what, but we found noise was no issue.
From entrance, it's a walk up to the 2nd floor (2 staircases up) but wide stairways made it easy to carry up our suitcases. From there, the entrance floor has twin/twin br and bath then it's a spiral staircase to get to living room, kitchen, master bed/bath. Upstairs shower was tiny so we all used the one downstairs and it had good water pressure and plenty of hot water. Good A/C which was nice after long warm walks in the city.
We used them to book us a sedan to/from the airport for 50 euro - about 40 more than a cab and a nice black Mercedes both ways. Worth it for us. Only downside was the the whole place could use a good wipedown - dusty floors, etc. but kitchen was clean and baths were clean, linens were nice, etc.
