Myself and a friend recently stayed here (September) so that we could attend a wedding in St. Pauls. I would definitely recommend the place - it is great value for money. The studio we had (number 3) was basic but it was very clean and had everything we needed. The location of the rooms is excellent! You are right in the heart of Lindo's and just a stones throw away from the beaches (both Lindos main beach and St. Pauls).
Check-in was very easy. We were met in the square, even though our flight was delayed and it was very late, and taken to the studio. If we had any problems, we knew the owners were available - they have a shop just around the corner. Both husband and wife are extremely friendly and welcoming.
The only thing about our 'studio' is that it is the only one that doesn't have a toilet/bathroom in the room. But we did have our own private one (we were the only ones with the key) just outside. It didn't give much privacy but we didn't find it a problem and we were clearly told about this beforehand so it was not a surprise.
I liked that there was a little patio /veranda area outside.
All in all, we would definitely stay here again.
