I had a very pleasant stay at Residence Martin, didn't really meet Nycolas, but his partner Veronica and little Lucas were lovely, very helpful and easy going. The appartment was comfortable, if a little thin walled and on a busy street - ear plugs recomended. I could imagine if all of the rooms were being used it would be a little crowded, esp, bathrooms etc, but while I was there in November (shoulder tourist season?) it was fine with just three others there sharing a room between them. I very much enjoyed the stay, central location (there is a nice food market right across the road for tasty local things!) and the accomodation. Nycolas works at a local trattoria which I thought was very good, worth a visit. Overall, the place is definitely recomended, just bring your ear plugs!
