We stayed here for 2.5 weeks for a cycling vacation. Great location in the heart of old town, just a short walk to cafes, coffee, bakeries, gelato, and shops.
The staff at Sleep & Stay were all very helpful and nice.
The mattress was super comfortable!
There is always a lot of street noise from people and workers in the street. This is not unique to this property - it's everywhere in old town. But the windows in this apartment seal out almost all noise, so when you tire of the noise, which can go late into the early hours, just shut the windows and turn on the AC. The only way to avoid the noise of the town is to not be in old town. We were there during Temps de Flor, so the town was a lot busier than normal.
There is an elevator, and it is small. Big enough for two people though. We even used it to bring our road bikes downstairs, by taking off the front wheel and holding the bike vertical. It's tight and tricky, but it works.
My only small complaint is the coffee maker. It's a Dolce Gusto machine, sort of like a Nespresso machine, but the coffee it makes is not as good as Nespresso (sorry, but I'm a bit particular). We did take advantage of it, but the "good coffee" is at the nearby espresso bar.
Overall, we LOVED this place and the staff!
